Hi @amy.blais,

I used the official Docker install guide: GitHub - mattermost/mattermost-docker: Deprecated
I have uncommented the edition line and my ports are:

ports:
  - "9280:80"
  - "9281:443"

I am using Plesk Onyx (newest release) and I set up a ‘proxy rule’ for my domain. (port 443 → 9281). My console shows errors like:

29920#0: *1578140 recv() failed (104: Connection reset by peer) while reading response header from upstream
