Me and a couple of friends were playing on the world of one friend who was playing aswell, since he hosted the world (not realm). When I got off after some time, I logged of on top of a bed. When I came back a couple of hours later, the error Message „unable to connect to world. Connection timed put." was starting to pop up after a very long loading time every single time, that I tried to join my friend (host). I tried many things like signing out and in again as well as restarting the game and console. After some testing, I realized that i can join friends that play on playstation. Unfortunately I can not join my friends that play on PC. The progress, that I had achieved up to that point is basically gone now. I had not changed anything about my network, nor my Console and Game. According to the Host, no settings were changed and nothing was altered since he was off as well when I was. Unfriending and adding each other again was also nothing of success. I hope this won't happen to anyone else. I still don't understand why and how this issue happened but I hope this will be fixed soon.
