When you say some time, how long do you mean?
This install is running on Linux. It used to be a manual install using Apache/mysql. When i updated to 1.8.2, I swapped it over to Docker. When 1.8.10 came out, I updated it okay. It has always been fine and the CMS accessable.
When I got this issue the other day, we really needed to change some of the content on one of the displays. After trying lots of things, the only thing I could think of doing was reverting back to the 1.8.2 backup I made. This resulted in a working system and I was able to change the display I needed.
Yesterday morning I installed some more RAM in the server thinking that it might help the maintenance to run quicker, but since the server was turned on, if I run ‘docker-compose logs cms-web’ it still says it is running maintenance and I get the proxy error if I try and access the CMS. I have come in today to find that it is still in the same state, should it take this long?
