Unable to connect to my realm

Recently I’ve been encountering a bug that doesn’t allow my friends or I to connect to my realm, it says “unable to connect to realm”. However I can still join other realms just fine. I’m unsure of how to fix this. This has happened around the same time for three nights in a row, around 1-2am central time. It lasts for around 10-12 hours and then fixes itself. I’m just confused because I’ve never encountered such a weird bug.
