By default, MyChat WEB server uses TCP port 80 if you do not use encryption. If this port is taken, the program will try to use 8080, 8081, etc.

 

You can change it to any other port if there is any conflict situation with other services that use this port. For example, Apache WEB servers, Microsoft IIS, or something else.

 

If you use HTTPS encryption, then the default TCP 443 will be used but it also can be changed any time.
