This smells like lmhost or netsh to me - tied to localhost maybe? I don’t think it’s a SH issue due to having issues with minecraft too.

You can reset your network adapter using the following from an administrative command prompt.
netsh advfirewall reset
netsh branchcache reset
netsh int ip reset c:\resetlog.txt
netsh winsock reset
After resetting your computer, I expect one of the following to have happened:
Absolutely nothing,
Problem is fixed,
Your computer blows up.
