Nginx.http.sock not created

Installation
,
1

Hello,

I decided to leave phpbb few weeks ago to discourse.

I installed it on a Raspberry pi under ubuntu 22.04.
After numerous attempts to make it work behind Apache I decided to go with Nginx. (I need to run several small websites on my server…)

However, following this tutorial Run other websites on the same machine as Discourse

I have a Bad gateway error with the nginx log giving me a

connect() to unix:/var/discourse/shared/standalone/nginx.http.sock failed (2: No such file or directory)

I am not the first to encounter this issue. Some thread are trully old, others Nginx.http.sock never created did not received proper replies
I did restart several time Nginx (and the docker), saw somewhere that I had to set DOCKER_USE_HOSTNAME: true and I did a chmod -R 777 on /var/discourse/shared/standalone

I am not the biggest specialist around but for the last 25 years I have been able to run different programs on servers (I am pretty new to dockers), I would be delighted to continue on this way if anyone could assist.

Thanks a lot,

PS my yml :

I would start by following Discourse on a Raspberry Pi | Blog without a reverse proxy.

Thank you very much @pfaffman
It looks like the issue was a forgotten chmod 700 on container.
At the moment, Discourse works behind Nginx on a raspberry 4. I hope it will help the people involved in the other unsolved threads.
