Support intro
Sorry to hear youâre facing problems 
help.nextcloud.com is for home/non-enterprise users. If youâre running a business, paid support can be accessed via portal.nextcloud.com where we can ensure your business keeps running smoothly.
In order to help you as quickly as possible, before clicking Create Topic please provide as much of the below as you can. Feel free to use a pastebin service for logs, otherwise either indent short log examples with four spaces:

Or for longer, use three backticks above and below the code snippet:

Some or all of the below information will be requested if it isnât supplied; for fastest response please provide as much as you can 
Nextcloud version (eg, 18.0.2): 19.0.4.2
Operating system and version (eg, Ubuntu 20.04): Raspberry Pi OS (arm64-2020-08-24)
Apache or nginx version (eg, Apache 2.4.25): 2.4.38
PHP version (eg, 7.1): 7.3.19-1
The issue you are facing: Something on my Nextcloudpi server crashes regularly. When I then try to access my cloud using the web address or ip address, I get the error message 403 Forbidden. In this case the Raspberry is not reachable via SSH anymore. As soon as I disconnect the Raspberry from the power and restart it, everything works fine again. The error occurs at least once a day and I can neither reproduce it manually nor can I see if there is a connection to any action. Iâve already searched the forum here, but I couldnât find an entry with the 403 error, which disappears after a restart. I would be happy to provide more logging information if needed. I would be so happy if somebody got a solution for my problem. Iâm so damn close to my perfect Nextcloud. Greetings!
Is this the first time youâve seen this error? (Y/N): No
