It was after, if I remember correctly.

I didn't change anything in Mattermost, just added the listening port on the container in Unraid.

I found you need two things for the recommended RTC udp port forwarding solution to work: 1. Port forwarding UDP/8443 in firewall to the Unraid/Mattermost server 2. In the Unraid docker deployment page for Mattermost, manually add another listening port with 8443. (bottom of page + Add another Path, Port, Variable, Label or Device) Config Type = Port. I just named it RTC listen port and put 8443 as Container and Host port, Connection type UDP - then Add and Apply. Make sure 8443 is not taken by another container, or you may need to change the listening port in Mattermost call app config.

Some permissions get reset on reboot, it looks like. Set permissions on subfolders, leave parent folder as is. Apparently only the top folder is affected and Unraid does not touch the subfolders.....

Same issue here with a Mealie stack......happened after the last Unraid update I think....

Starts up and I'm able to log in. But get errors when I try to change or add something in settings. Did not try uploading stuff. I ended up adding more cache pools, one with spinning disks and btrfs, where I installed without errors.
