Error

Error #0315: encryption is impossible. The operating system is too old
 

Error description

Can't enable encryption for connecting to MyChat Server, and use HTTPS-connection to transfer files because of outdated version of the operating system (Windows XP, Windows 2000, or Windows Server 2003).

 

MyChat Client continues working without traffic encryption.

 
Problem solution

OpenSSL encryption library that we use for traffic encryption can't work on outdated Windows operating systems.

 

You need either update the operating system, or give up on encryption with your MyChat Server.
