Hi, I just started trying NextCloudPi on a Raspberry Pi 3 a couple of days ago but I keep encountering some issues.
I installed NC 18 by flashing the official image into a micro SD card for the pi. I plugged a 500 GB hard drive through a powered USB hub connected to the pi. It is only accessible from within my house network. Also keep in mind that I have virtually no knowledge of system administration, servers, databases or the like. I know Python and zero php.
My issue is that the server seems very unstable and can crash by very simple actions. The most common is when I attempt to download an item from the server to my computer or to my phone using the app, the server will crash. However, it does not happen all the time. It seems to happen mainly when the file to download is bigger than 70 MB in size. In these cases, I need to reboot the pi and it will restart and everything is fine until I need to download a file again.
Sometimes when downloading multiple items, I will get a zip file containing only a subset of the files and sometimes some files like videos get partially downloaded.
Also, I’m not sure if it is related, but I can never play videos directly from the server and they don’t have thumbnails from the web view. A few times when I click on a video to stream from the server, it will only playback the first 1 or 2 seconds and stop or the server crashes completely.
Just now I attempted to download a 90 MB video file that I have on the server and it only managed to download a few seconds (only 7 MB) and then the server crashed with the following message on the web view:
Internal Server Error
The server encountered an internal error and was unable to complete your request.
Please contact the server administrator if this error reappears multiple times, please include the technical details below in your report.
More details can be found in the server log.
Below I am including the output of running sudo ncp-report on the pi through ssh right after the crash and before rebooting. I can see that it says it cannot find a file for datadir nor dbdir. However, when I followed the setup wizard it seemed to configure the disk correctly and I:

Your data directory is invalid
Ensure there is a file called ".ocdata" in the root of the data directory.
Cannot create "data" directory
This can usually be fixed by giving the webserver write access to the root directory. See https://docs.nextcloud.com/server/16/go.php?to=admin-dir_permissions

When I go to the admin panel on the web view I see under CONFIG in nc-datadir a green text “path exists”. The same with nc-database. However, if I click on the little refresh button, the path to nc-database changes to “/var/lib/mysql” and the text is now in red and says that the path does not exist. I will add some captures below in case they are helpful:
I should also add that uploading to the server has not caused issues so far, or none that I have noticed except once when it crashed while trying to upload about 50 files and 3 GB total but I uploaded them in three parts and everything was fine after.
I will appreciate any help I can get. It would be great to get this working reliably to have my own private cloud.
