Hi,

I tried for a while to setup the CODE server on my docker host. I did everything exactly as in the tutorial (adapted to my domain) and the reverse proxy is also properly set up. However, I am not able to perform any connection to the CODE server. Neither via https nor by http on port 9980.

I did use the search and couldn’t find anything. Since I’m sure I’m not the only person with that issue, help is very appreaciated.

That’s how I launched it:  
docker run -t -d -p 9980:9980 -e ‘domain=my-nextcloud-domain’ -e ‘dictionaries=de en es …’ --restart always --cap-add MKNOD collabora/code

My logs look pretty much like this:
