We're not able to log onto our Java Realm. There are 4 of us with access and we're all experiencing the same issue - after clicking 'play', we get 'connecting to realm' for a while, then the error 'An error occurred, please try again later.
I've tried closing the realm and re-opening it and shutting down Minecraft and re-starting it.
This appears to be a duplicate of REALMS-5600, which was later fixed. You should no longer experience this issue.
