Stuck on the "Connecting to the Realm" Screen

I am using Java Minecraft version 1.16.3 to play Realms. I was able to join and play on my server yesterday fine. However today when I tried to log in I got stuck at the connecting screen. I let it run for a long time and it never connected.

I am connected via Ethernet so it is not a connectivity issue.

Two of my friends were able to get on with their accounts. One of which using the same internet as me. Please help
