Mapping different 80/443 ports prevents image upload/manifest creation

[mhpob]

I have other applications that I would prefer to use 80/443. After changing the mapping of the ports in the docker compose file, the application runs, but I cannot add manifests/upload images -- it returns 403/57. If I map it back to 80:80, everything works fine. Is there something else I should be changing?

Creating manifest:

tiny-iiif-nginx  | {IP} - tiny [20/Feb/2026:17:14:25 +0000] "POST /tiny/api/manifests HTTP/1.1" 403 57 "http://{IP}:1234/tiny/" "Mozilla/5.0 (X11; Linux x86_64; rv:147.0) Gecko/20100101 Firefox/147.0" "-"

Attempting to add an image:

Thanks for creating this, installation and running was incredibly easy!

Hm, interesting. You just re-mapped the outbound ports for NGINX, right? (Keeping the internal ports inside the containers the same.) That should work. But I haven't tried it myself yet. I think there's probably small extra config missing in the NGINX default.conf file. Since the file currently presumes the default ports, there's probably something going lost in the proxy_set_header forwarding rules. Might be worth a try - but I'd need to troubleshoot myself to be sure what's going on.

[mhpob]

Ah, yes! That info + a flurry of searching led me to change proxy_set_header Host $host; to proxy_set_header Host $http_host; and to drop proxy_set_header X-Forwarded-Port $server_port;. This now works!

I am not experienced in this and don't fully understand what is going on here or if it has any other ramifications... so be skeptical of that fix.

I'm not an expert in NGINX config either. If it works - that's a good sign 😀 I'll dig into it and will do a bit of testing myself.

Hi there!

Really interested on this project, congrats on all the good work!

I'm also looking into easier ways to configure custom ports, will be following up news here :)
