Docker Compose Nextcloud Hangs on boot

[jray06]

I'm having a heck of a time with an initial installation of nextcloud. Running from docker-compose on an Ubuntu VM behind traefik 2.1. DB is mariadb tag is pulling 10.5.13 from linuxserver.io's image + a standard redis image. No matter what I do, my log hangs on container start. Very similar results as @nodeswitch in issue #1455. Log file below: (note the last entry is hours after container start)

The only other relevant thought I have left is that I'm feeding the nextcloud container a "nextcloud " database user/pass on mariadb with all global priviledges instead of the root db user. Still, I would expect to see some semblance of progress in the logs regarding mariadb if this was the case, so I don't think it's a db connection issue.

I've already re-pulled the nextcloud image, to no avail. Thoughts (comments) and prayers appreciated ...this one has me stumped.
