Can't get into realm, after "Intializing upload" failed.

After making a copy of a realm, then trying to re upload it back to the realm. The error screen popped up after trying to upload. However when trying to get back into the realm, it would not let me back in and intead would show another error message saying, "failed attempting to join realm". I tried using my cloud saves, but it kept giving me another error message saying it failed.
