I tried to install the 2.6.0.beta2 update yesterday via SSH. The update itself runs without problems. I also read the information, that the update can take a long time. But after a day, it should work again. I also have a view thousand posts. So it is not a realy large forum…
I also removed all plugins and restarted a rebuild. No change. The Docker container is running. Also the database and also the websocket. But I get a 502 error from the nginx server in front of the docker container.
Any ideas how I can start do debug the problem?
