As MyChat Client can work even on outdated operating systems (Windows XP, Windows Server 2003, etc.) where TLS 1.3 does not work and no root certificates from modern certification centers, that causes an issue with update uploading and file/image transfer in a chat.


If you enable HTTPS encryption on a server then a client application installed on an outdated OS can't download or transfer a file to a WEB server.


To solve this issue, launch another simplified WEB server that listens to TCP 8090 (by default) but without encryption, special for supporting old operating systems. This port does not allow entering all WEB services, only works for downloading updates and files in a chat.


You can change this port. Do not forget to set it up on your router (port forward or port mapping) when connecting to the server via the internet.
