I've recently been unable to join my usual minecraft realm. Its been a intermittent problem, occasionally i'll be able to join. As of this morning I cannot join whatsoever, it either gets stuck at "Loading resource packs" or after about 20 seconds "Unable to connect to world"

After looking at other possible solutions I've restarted my network. Enabled Upnp. Even set the console outside of my routers firewall, and reinstalled Minecraft.

Nintendo Switch OS v8.1.0 - Minecraft v1.12.0

Just now running the connection test on the switch, I have a Open NAT Type, Download - 17.4Mbps - Upload - 5.8Mbps.
