Token problems with version 8

I’m currently using version 7.0, and everything works great. Now I’d like to update to 8.0. When I update my Ubuntu server, I get WebSocket errors. It seems others are having this issue too. So, I installed version 8.0 on a fresh Debian installation, and everything runs smoothly.

However, I have a problem with the JWT token. When I deactivate it, everything works. I followed the instructions in the guide, entered my secret in the local.json config file, just like on my other server with version 7. But no matter which secret I use or how many times I restart the server and all services, I always get an error message saying the secret is incorrect whenever I try to access a document. Can anyone give me a tip? Do I need to generate the token differently for the new version or something? I even use the same secret as on the old server and generated a token that version 7 accepts without any problems, but with version 8, it doesn’t work.

Please provide the following info:
