I have a realm with a group of friends. This was not an issue before 1.17, as we created and tested it out. So the basis is that we created a nether portal hub to connect a portal at spawn to a portal at our base. It worked and we were able to go back and forth between our base and spawn. After 1.17, I tried to go through like normal. I could get through my portal and journey through the nether, but when I try to go back through the portal, it crashes the realm. The screen dims and the purple particles float around but it never goes to the loading screen. I have tried 4 different time, with a friend online and with just myself online. It crashes every time. Then, we are not able to get on for another 10 plus minutes because it is unable to connect.
