Not sure if this is the correct place to post this but, I have scoured the internet trying to fix my problem with my nextcloud install using OMV5 in docker with a protainer stack. I followed a video that Techno Dad Life posted and also referenced this tutorial from user Macom. After completing the setup, I can access the nextcloud webpage but, I get an error when trying to create an admin user. The error I'm receiving is below. I'm running OMV5 on a rpi 4.
Error while trying to create admin user: Failed to connect to the database: An exception occurred in driver: SQLSTATE[HY000]  Access denied for user 'root'@'nextcloud.nextcloud_default' (using password: YES)
