Forge Server Error - '[Forge Version Check/WARN][ne.mi.fm.VersionChecker/]: Failed to process update information'

[Morgan Somerville]

I'm unable to join my local forge servers.
When running my forge servers of seemingly any version (tested 1.18 to 1.21.1) I get an error message [Forge Version Check/WARN] [ne.mi.fm.VersionChecker/]: Failed to process update information
The server continues to start up and run, however I'm unable to join.
Looking for solutions?

Full error message: (note last "thead warning" error seems to be unrelated and only happened once for 1.20.1)
Forge version check warning has happened for every version.
