Hi,
I have Nextcloud installed on my VPS alongside many other apps and everything was working well until I installed Collabora Online - Built-in CODE Server. Now, I am unable to open my NextCloud instance, it takes too long loading the site and ends up with a (edit: 504 Gateway Time-out). I tried visiting other websites on my server and none of them is working anymore. I ssh into my server and I deleted richtdocumentsserver from Nextcloud’s app directory, but this didn’t solve the issue. Any suggestions on what might be the cause of this issue and what are the recommended solutions.
