The story so far.

On Sunday, I was still able to connect to my Realm and do things. Later that evening, I performed a wipe/reload of Windows 10. Since then, I've been unable to connect to my Realm.

However, this issue is only related to Realms. I can connect to all the public servers I've tried just fine. I can download my map backups from the Realm too, and perform other administrative things... I just can't actually connect to it and play.

Below is the pertinent portion of the log file illustrating an attempted connection and subsequent failure. I've sought help via email and on the community support discord server, and I really don't know where else to turn or what else to do, since the realm I'm paying for can't be accessed.
