I've been trying to set-up Nextcloud via Docker on my RPi for a few days now. I've been following the installation guide from @TechnoDadLife - Nextcloud, your personal cloud server, Openmediavault. I had to change a few things with the Docker installation so it would work for my RPi. For example, I had to use lsioarmhf/mariadb and lsioarmhf/nextcloud instead of linux/mariadb, linux/nextcloud. And I still have to figure out how to work with sharedfolders on my Luks encrypted drive. But other than that it seemed to work. At least, that's what I thought...
Nextcloud seems to be running fine, but when I try to create an Admin account I get a 504 Gateway Time-out Error. When I retry this I get all different kinds of errors, like the one below.
I've repeated the steps several times and at one point it was actually working, but I messed it up again after a reboot, because of my Luks encryption. I've tried it again a few more times, but I kept getting the 504 Gateway Time-Out error.
I found out it had to do with nginx and followed this guide to change the max execution time limit, but that didn't help.
Any suggestions how to fix this? Or maybe my RPi isn't capable of running this?
