Whenever I try to log into my realm, it takes a few minutes to load and then I spawn in the same place that I guess the realm's latest backup is set to. I break some blocks to see if it's laggy and it usually isn't at first, but then within a minute or two it will stop loading chunks and won't let me go anywhere else other than the areas that have loaded which aren't very many, and then it'll disconnect me and everyone else on the server. I've tried replacing it with a new map, tried resetting it, nothing works.

I haven't been able to play on my realm since the 3rd of October, and I've checked every day to see if I can, and I haven't been able to.
