Connection timed out : getsockopt + Internal Exception : java.lang.IndexOutOfBoundsException

[Rosiiiie]

Hello , I'm trying to play Minecraft with friends via World Host , but when they try to connect to the server they get one of two errors : " Connection timed out : getsockopt " , or " Internal Exception : java.lang.IndexOutOfBoundsException "

I'm trying to host the world on my Steam Deck using the DeckCraft modpack , which comes with World Host preinstalled .

Minecraft Version 1.21
World Host Version 0.4.14

In my logs it states that Polytone and Sodium aren't compatible with eachother , however the game opens and runs perfectly , other than World Host not working .

edit - updated my logs as I did not upload the correct log file

Try disabling UPnP in your settings.

We have already tried disabling UPnP , but to no effect .
