Xbox authentication doesn't work on LAN

Starting from around yesterday Minecraft and Xbox authentication stopped working on all devices in my network connected via LAN.

This problem doesn't seem to persist with any other applications OR with devices connected to WIFI. I would assume its an issue on my part, but from everything I've tested it seems to happen ONLY when trying to log into the Xbox app and Minecraft, everything else works just fine.

Would love some help with this. Sorry if this isn't the correct section for this
