Greetings,
I realize that the supported version of Discourse requires a specific set up, however…
My curiosity and amount of work put in thus far compels me to ask for help here.
I installed docker on an AlmaLinux VPS and installed Discourse, had it running and set it up, invited users, all was hunky-dory. I’ve not added any plugins or made any major modification beyond the front-end interface changes.
And then I did a security update for Discourse that came through yesterday (or the day before).
It all went smoothly.
This is where the rookie mistake happened (I’m a rookie when it comes to this for sure). I decided to change my SSH port and forgot to open that port in the firewall. Well, after I fixed that I tried to restart Discourse and…
FAIL
Anyway, here are some of the errors (let me know if there is hope, or if I’m missing the obvious, or whatever. Be gentle 
:
