Docker Image behind NGINX, error 400

[axenn]

Hi,

I tried a lot but i have always a 400 error, i don't understand why.

At the begining i  modified my config file to have upstream to another webapp image i have, and it worked perfectly. At the end i followed the NGINX tutorial and user 127.0.0.1 as the docker container IP, problem still the same.

I would to user it from wan.

Sincerily.

Set the IP to the actual IP of the jellyfin container. Depending on your setup, 127.0.0.1 won't reach Jellyfin.

hi, thank you for your answer.

as a dumb i wrote the wrong port, i didn't set the default port in entry for the docker image.

Now i changed it, it's a 502 552 error.
I removed SELinux for the while, but it's not enough.

For the ip i modified 127.0.0.1 to try with the one used by the docker in its subnet, but problem remains.


PS: bridge mode configuration

ok i think i found... it was a 400 finally.

i set the line : 'proxy_set_header Host $host;' BUT ... There were a little space just before 'HOST'.

I understood it by wanting to install a certificate with certbot despite the fact i could'nt connect, just to see if there were a limitation somewhere by not using ssl.

Nginx -t didn't see any error. But Certbot said me 'Could not parse file: /etc/nginx/conf.d/XXXX.conf due to Expected stringEnd, found 's' (at char 0), (line:1, col:1)"
