Browser returns 504 error after browsing Nextcloud on web

[ultimaterez]

After browsing my Nextcloud instance for 1-10 minutes the page becomes unresponsive and eventually returns a 504 error. It will stay in that state until I let it sit for 30+ minutes or I restart the container. I can't seem to find anything in the logs that indicates what could be going on. Any help or ideas on where to look for the problem would be greatly appreciated!
