It seems I crashed discourse while changing some settings related to categories
Initially I was trying to remove all options from Top menus. As I was getting an error saying that I can’t remove “latest” from top menu, I changed “category style” to “Categories only”. Then I removed all top menus. However my discourse became really unstable and finally I ended up getting “Error 500”.
In the nginx logs, I can see some “connections refused”. We tried rebuilding the container, restarting the whole machine. nothing worked.
