MyChat Client error #0230: port for the service "XXX" matches the service's "YYY" port "NNN"
Error
Error #0230: port for the service "XXX" matches the service's "YYY" port "NNN"
Error description
It turned out, that you saved MyChat Server network settings, and a network port of a specified service matches with the same port of another MyChat Service. This is unacceptable.
Problem solution
All MyChat network services are bonded to a specified port. These ports can't match. For example, you can't use 2004 port for connecting clients to the server and for built-in WEB server.
Choose another non-busy port and save the settings again.
