I'm able to play on singleplayer

Both singleplayer and multiplayer work differently which doesn't make it an valid comparison.

I can't see any connection attempt to the server. Try connecting to the server then share the log

https://mclo.gs/XmHUmDD If this isnt right then i dont know how to fix it(in the sense that it says i did not connect)

Try connecting to the server and once you get the error, close the server then share the server log

The seems to be an connection attempt but it doesn't show the username of the player trying to join. The log seems to be weird. Did you install all the mods from the server to your PC with the exact same versions?

If your sure that the mod versions match then try deleting the config folder. If non of the steps work then try removing mod by mod till you stop facing the issue
