Description:
You will be asked by the Scoring client (iPhone or Android) to enter the unique server IP address every time you configure (reconfigure) the mobile referee client. The configuration is saved in your mobile. You don't have to configure again your mobile every time you restart your mobile.

Reason:
Every computer (server), mobile phone or table has a unique Internet Protocol or IP address which identifies the server in your network. In the currently most widely used version of the Internet Protocol (version 4), the IP addresses are 4 bytes long and are expressed in the form nnn.nnn.nnn.nnn. Each nnn is a number between 0 and 255. The Servet Address is requierd by the client in order to connect to the server. Each server has a unique address as any web server you use to browse in internet.

Reason:
How the server auto-discovery works?
The server auto-discovery used in your phone (or tablet) makes use of the standard network multicast protocol. Well, multicast is a protocol designed to allow a single device to communicate with a set of hosts.
If any of your used devices: phone, tablet, access point, router or PC are not supporting (or are blocking) the multicast messages, your devices will not be able to receive the messages from your server.
Is there a way to tell if multicast is broken or not supported on some devices? The simple answer here is NO. There seems to be no easy and reliable way of telling you if multicast works on a device. Some devices simply fail silently with no error messages.

Reason:
How the remote display works? The remote display makes use of the standard network multicast protocol. (The same method used by Android clients for server auto discovery).
Well, multicast is a protocol designed to allow a single device to communicate with a set of hosts.

If any of your devices (phone, tablet, access point, router or the PC hosting the server) are not supporting multicast or are blocking the multicast messages, your remote display will not be able to receive the messages from your server.

Description:
You are using the trial mode or you have a single licensed mobile registered with your server. You click the red or blue button and the control light blink one time on the server screen. No score is changing.

Reason:
The most common reason this issue is if you setup the minimum number of referees to score almost on the same time to a number higher than 1(one).

Solution:
You cannot set this number higher than the number of referees you registered. Please change to value to one (1) and try again.

Description:
You have more licensed mobile referees scoring. You click the red or blue button and the control light blink one time on the server screen every single time you touch your mobile screen. However no score is changing even all the referees are clicking almost on the same time.

Reason:
You can set the number of judges that have to press almost on the same time a red or blue button within a predetermined amount of time to score a point in your server console. Also you can tune your predetermined amount of time the referees should press the buttons to validate the score points.

There are two most common reasons for this issue.

• if you setup the minimum number of judges to score higher than 2(two) or the total number or referees;
• if your WIFI network or your server are too slow and they cannot process the information just in time;common reason this issue is if you setup the minimum number of referees to score almost on the same time to a number higher than 1(one).

Solution:
You cannot set this number higher than the number of referees you registered. Please change to value to one (1) and try again.

Description:
You are using the trial or competition mode. You click the red or blue button and the control light doesn’t blink and no score is updated.

Reason:
The most common reason this issue is a WIFI network communication.

Solution:
Be sure the network connectivity for server and clients woks properly and the mobile clients are correct configured.
To open these ports is mandatory for our application. In order for the system to work property, be sure your Wi-Fi Access point or firewalls don’t block the traffic for any of the following TCP ports:

• 12357
• 12346

Description:
This message appears because the License used by this mobile device appears to be already in use for a different mobile. A Unique Mobile Client Access License that legally permits mobile clients to connect to the Scoring server is required for each device.

Reason:
The most common reason this message can appear is if you upgraded your mobile device recently and/or you are using the same mobile owner email address for more than one device.

Solution:
If you recently replaced or reinstalled your device and you are the owner of the licence, please remove the old registration from the Scoring Server in order to re-register this mobile device.

Description:
This message appears on the mobile client screen because the mobile application fails to communicate successful with the scoring server. No control light blinks on the server screen for this referee and no point will are scored by this mobile client.

Reason:
The most common reason this message can appear is if the server is not started or there is a problem with your WIFI network.

Solution:
The server must be running before a server application can be accessed. If the error message is received every single time you click the red or blue button is very likely to be a problem with your server; verify first if the server is running. If it’s running please check if other mobile users can still connect.

• If other users can connect, restart your mobile and try again. Be sure your mobile is connected to the same WIFI Access Point and there is no firewall that the communication between your mobile and the server.
• If the other users cannot connect too, than restart your server and try again.
• If your Access point supports dual mode (2.5G and 5G), deactivate one mode and connect all devices to the same Access Point using the same protocol.

Description:
You click the red or blue button and you receive the above message. Your servers list is empty.

Reason:
In order for a mobile client to be usable it has to be registered with a Score server. The most possible causes are:

• The application was just installed
• You removed all servers you been registered with from your servers list
• Your subsection was removed from server by the server administrator.(You have to register again)

Solution:

• Start the server.
• Navigate to the 'Referee Setup' panel. You can reach the panel in the server menu bar.
• Once the server has successfully entered this panel, please click OK and close this window
• Wait for the device to scan the network for the servers.
• Select your server (court) from the servers list if more than one court is used.
• Click "connect" and wait for the application to respond. The server registration may take up to one minute.
• Your mobile will try to register with the selected server.

Please note:
Any time you have to register a new mobile device with a server, the server must be opened in 'Referees Setup' panel in order to proceed successful.

Description:
You try to connect a mobile client with a new server. The server is successfully discovered by the mobile client. You select the server and click 'Connect'. After a few second you receive this message and the registration fails.

Reason:
The server admin has to have access to control the registered mobiles. To be sure nobody can register a new mobile without the admin acceptance; the server must be in 'Referees Setup' mode in order to proceed.
At any time you have to register a new mobile device with a server, the server must be opened in 'Referees Setup' panel in order to proceed.

Solution:
To get started:

• Start the server.
• At the server console navigate to the 'Referees Setup' panel. You can reach the panel in the server menu bar.
• Once the server has successfully entered this panel, please close this window, and try to register your mobile client again.

Please note:
At any time, in order to register successfully a mobile client device with a server, the server must be opened in 'Referees Setup' panel.

Description:
You try to select a mobile client with a new server. You opened the server “Referee Registration” panel. The server is successfully discovered by the mobile client. You select the server and click ‘Connect’. After a few second you receive this message again and the registration fails.

Reason:
When this issue happened to us we were trying to connect to a wrong server. We had a server running in background in one of our mobile devices having the same name as the server we were trying to connect.

Solution:
The full guaranteed solution to make sure the server is not running in background in any of your devices is to restart all your mobile devices and any Laptop or PC you are using. After you reset all devices please try again.

Description:
You try to select a mobile client with a new server. You opened the server “Referee Registration” panel as per our instructions. The server is successfully discovered by the mobile client. You select the server and click ‘Connect’. For some mobiles takes just 1 to 3 seconds for registration. The other mobile the registration is timing out or takes up to 30 seconds.

Reason:
You may have a firewall in your mobile device, in your server or in your Wi-Fi access point block some of the TCP/IP traffic. Our wireless client/server application is using TCP/IP communication and if any of the components blocks the traffic the mobile will not be able to connect to the server.
The Server discovery, Server registration and Server connection during the game are using different protocols and it is possible to get working the discovery but to not be able to register or use the controller after the registration.
In order for the system to work property, be sure your Wi-Fi Access point or firewalls don’t block the traffic for any of the following TCP ports: 12357 and 12346 These ports are required by our application for communication.

Solution:
To open these ports is mandatory for our application. In order for the system to work property, be sure your Wi-Fi Access point or firewalls don’t block the traffic for any of the following TCP ports:

Description:
You try to connect your new mobile client with a server. You opened the server "Referee Registration" panel as per our instructions. The Auto-Reconnect is disabled. If auto-reconnection is enabled we recommend to temporary disable it. The server is successfully discovered by the mobile client. You select the server and click 'Connect'. Some other mobiles connect successful. This mobile time-out or the application fails to respond.

Reason:
One of the reasons may be Auto-reconnection function. The client is trying first to stop and remove the current server connection. After the current connection is successfully closed (or deleted) the client will start the new mobile registration.
The Server discovery, Server registration and Server connection during the game are using different protocols and it is possible to get working the discovery but to not be able to register or use the controller after the registration.

Description:
The default rules configuration is following the WTF rules (1,2,3,4). IFT competitions are not using the same rules as WTF to award points for kicks. To use it for an ITF competition you have to change the number of points awarded by the server for each button event.

Reason: Organizing competions for ITF clubs

Solution:
Starting with version 3.1, the TKD Scoring Server Wi-Fi (Tablet and PC) supports events score customization. You can find the options to change the default point for each click or swipe in the server "Game Option" menu.

To use these functions you must use a TKD Server version 3.1 or later. No upgrade to controllers is required.
