If you cannot connect to an already configured server, please check the status of the server first. You can do this using the following command:
omixon-hla-server-executable status

If the server is not running, please start the server and try connecting again.

If the server is running please check the next section.For newly installed servers, the most common issue is misconfiguration. If you cannot connect to your server, please check the following things:

• In the client’s connection configuration, ‘Server host’ must be set the exact same value as ‘-Domixon.server.host’ in the server configuration file.
• Make sure that the server hostname resolves to the same IP on the server and client machines otherwise the clients will get a connection refused error. It is a common configuration problem that the hostname resolves to a different IP on the server (e.g. to 127.0.0.1 via an internal network interface) which causes connection deny.
• It is always safe to specify an exact IP address both for the server and clients which is reachable from all the related machines across the network.
  Verify that the set port and the next one are both free for use on the server and client machines.
• If no issues were found using the checks above, please contact your system administrator and ask for firewall settings that can interfere with the connection.
