Docker: Nextcloud cannot communicate with MariaDB

I have the same problem. Installed on ROCKPro64, lsioarmhf containers.
How to solve this problem?

Can you provide Screenshots of your containers?

Pictures for some reason are not inserted ...

try entering nextclouddb in the field which is formerly called localhost

Unfortunately the error is repeated ...

try:

• Database user --> "root"
• Database password --> "passone"
• Database name --> "nextcloud"
• localhost host --> "nextclouddb"

I was in a hurry. The problem was access rights to the AppData folder, which the author did not mention in his video. After setting full access rights for all users, the problem was resolved. And instead of Localhost, I entered 192.168.10.21 (my IP address): 3306

Thank you very much. I will try!

Please tell me what permissions the AppData, Nextcloud (inside AppData), Nextclouddb, Nextcloud (at the root) folders should have. Like on a picture.

If your enter the PUID and PGID correctly when setting up the linuxserver container there should not be any permission problems

And what user data needs to be specified? Root, admin, or do you need to create a new user? And all the same, if not difficult, please show your settings.

To set up the containers you should use the up to date guide by @macom

Hi,

I am sorry to ask this (very likely) newbie question:
Following TechniDadLife Tutorial for Nextcloud (

Code

Error while trying to create admin user: Failed to connect to the database: An exception occurred in driver: SQLSTATE[HY000] [2002] Connection refused

MariaDB is running and both are, judging from my not knowledge, in the same network when I check it in Docker.

When I check the MariDB Container Log I see "Warning: World-writable config file '/etc/mysql/conf.d/custom.cnf' is ignored" - might this be an issue?

Any suggestion to fix this is highly appreciated, thanks a lot in advance!

So this happened to me, but I think the reason is because I am using an ntfs formatted disk plugged into a Raspi 4. ntfs appears to be run from Fuse and thus all perms are 777 (owner/user/other read/write/x) so this is why I think I am getting this error. I'm not sure how to get around this other than start over with another drive possibly formatted as ext4 since it's a 4tb drive.

For me the primary reason to use OpenMediaVault is for a secondary backup location w/ Sharing capabilities, and ntfs does make it easy to just unplug from OMV and plug directly into a Windows or MAC so I'm not keen on changing.

Maybe there's a workaround. I have a few ideas..
1. There's a 32g card in my Raspi 4. OMV only uses 2g or so. I could run fdisk and reclaim some space and use 20g or so for a small partition to run on ext4 fs and let Nextcloud run from there
2. Use a powered USB hub and plug in another disk formatted to ext4 and install NextCloud there.
3. Perhaps there's another way to coerce the mounts from /etc/fstab to get it to load differently, although I haven't messed with it yet.

Any ideas appreciated!
