Network error 10091: "Network subsystem is unusable"
Error description
The error usually occurs on a very poor connection, for example, a laptop's WiFi connection via a 3G hotspot and a loaded mobile network. In this case, there is a connection, but the delays are too long, tens of seconds.
Problem solution
Open the console. Menu "Start", "Run" (or Win+R), and type cmd:
In the console window execute the command ping <ip_mychat_server>
If there is a connection, make sure there is no packet loss. If there are losses or delays, you need to provide a better physical connection.
