Handshake issues

Incorrect or unreachable address

Incorrect address

Double check that the address you are attempting to connect to is correct. Usually an ip-address and port will look like this: 127.0.0.1:2700. If you are connecting directly, using an IP-address as shown, make sure to include the specific port (the 2700) you wish to connect to. If you are using a hostname then the port should not be added. A hostname can look like this: wss://socket.gryt.net.

Check reachability

You can check if the address is reachable by opening a terminal (cmd on windows) and executing the following command:

telnet <ip_address> <port_number>

Replace ip_address and port_number with the appropriate values and check to see if you are receiving a pong back. The default port number is 2700

If you are receiving connection refused it means the server ** is not reachable.** This can occur either because:\ A) The server is not open to the public (server's port is closed)\ B) You wrote the incorrect ip-address or port\ C) Your internet connection is unstable (very unlikely)

Example of reachable endpoint

sivert@Siverts-MBP ~ % telnet localhost 2700
Trying ::1...
Connected to localhost.
Escape character is '^]'.
^CConnection closed by foreign host.

Example of unreachable endpoint

sivert@Siverts-MBP ~ % telnet localhost 3521
Trying ::1...
telnet: connect to address ::1: Connection refused
Trying 127.0.0.1...
telnet: connect to address 127.0.0.1: Connection refused
telnet: Unable to connect to remote host

command not found: telnet

If you are on macOs and the telnet command is not found, try installing it using brew first:

brew install telnet
