So myself and friends have being playing on his realm for a few days now, I've been able to connect fine for days. But today, its just stuck on "Connecting To Realm". I've googled and have done multiple attempts to try and fix it without any luck. 

1. Restarted PC multiple times.
2. Run minecraft launcher as admin.
3. Restarted my router.
4. Unplugged enternet cable from pc, plugged it back in/
5. Connected to a Multiplayer server (works fine).
6. I have asked friends to try join the same Realm, works fine for them.
7. Allowed Java & Minecraft Launcher through my firewall.
