System.Net.Sockets.SocketException (0x80004005): A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond

I have got this error randomly. Sometimes it's working and sometimes it gives this error

Could you tell me what the issue is? I am using the 2020 version.

This is an error from the operating system upon initial connection. There's not much the library can do about that
