The client could not make a connection to the destination server you're trying to connect to. Either something is blocking the connection request or there is no server at the end.
- You entered an IP or port which is not correct or where no server is running on.
Check with the serveradmin if you have the correct IP and port and if the server is running. If the server doesn't run on the default port 9987, enter the destination address of the server like the following: IP:PORT or in numbers 192.168.1.1:8760 (this is just an example)
- You have a firewall which is preventing a connection to the server.
Check your firewall manual to see how to allow TS a connection to any TS server. The ports required by TS are mentioned in the FAQ. If this doesn't help you, check a firewall forum for specific help for your kind of firewall
- You can connect to some servers but not to the one specific.
Test several servers to make sure the problem lies not within your network configuration but on the server side.
The server hoster may miss a port forwarding or has a bad firewall config (this is often the case when new / network unexperienced user setup servers). Advice the hoster to configure the port forwarding.
- You get a timeout.
Some firewalls can cause timeout problems as well, so deactivate the firewall for testing. Wireless networks may as well be the cause of timeout problems. Try to connect without the WLAN and use an ethernet cable instead.
