Docker container not able to retrieve images

[Solapse]

When the device is trying to retrieve images I see:

nas url: http://192.168.0.252:32769
[ 4275][V][HTTPClient.cpp:242] beginInternal(): url: http://192.168.0.252:32769/download

Server error (500), will retry once...

The web config - I have : http://192.168.0.252:2283 as my url.

If I try: http://192.168.0.252:32769/download

I get {"error":"Failed to fetch albums"}

192.168.0.252 <- this the same device as the Docker image and the Immich instance (basically localhost). With a valid auth token (i.e. after successful web session login) on another machine: http://192.168.0.252:2283/api/albums is returning information in the browser.

Any ideas?

This is strange:

        "Env": [
            "IMMICH-API-KEY=XXX",
            "PATH=/home/app/.local/bin:/usr/local/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin",
            "LANG=C.UTF-8",
            "GPG_KEY=XX",
            "PYTHON_VERSION=3.9.21",
            "PYTHON_SHA256=xx",
            "IMMICH_API_KEY=your-api-key",
            "TZ=Asia/Taipei"
        ],

Seems the API key is being declared twice in the docker image environment variables

[Solapse]

Yes - this was the issue. I built the image from scratch with the API key added to the docker file and removed it from the docker run command. Needs a change to prevent this happening, or some updates to the docs
