Hey, could you check that agian with this build? I think i know why its happening but not sure, you can check if you can join through local ipv4 (the one in config or just connect to localhost as IP address) it should work as long as server is hosted in your local network. The issue seems to be in ipv6 handling, i am guessing that you used the forge lan auto search feature which joins you though ipv6 which seems to don't work with ported to forge fabric api networking module i am using...

Still getting the error with that build. I tried connecting through my local ipv4, and it still gave me the same error. My network is a bit exotic so that might have something to do with it, as the server is being hosted on technically a separate network than I am trying to connect from.

Still getting the same issue. Logs look the same as the previous times. I'll see if I can find a fix on my side, since it could possibly be to do with my network topography. I'll let you know if I get it fixed

Hmm try maybe that, this fixes it for me
automodpack-mc1.20.1-forge-3.4.4-SHAPSHOT.zip

If not please send new logs from server and client

Should be fixed in 3.4.4 if not write message here again
