Current behavior

When trying to make the API call below, the error No URL found with short code \"my-short-code\" for domain \"my-domain.com\" is returned...

GET https://my-domain.com/rest/v3/short-urls/my-short-code/visits?page=1&itemsPerPage=1&domain=my-domain.com

Expected behavior

I'm using a stable docker image, I think I may have configured something wrong.

However, my URL works, and visits are counted normally.

Minimum steps to reproduce

I did a new installation from scratch, generated an API key, registered a URL and tried to see the visits.

I've already figured out what it is. My shlink is running behind a reverse proxy and apparently the application can't find the authoritative domain of the link.

My container is called shlink, I have an nginx that exports 443 and 80. I do the following configuration for proxy_pass:

location / {
    real_ip_header CF-Connecting-IP;
    proxy_set_header Host $host;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header X-Forwarded-Proto $scheme;

    proxy_pass http://shlink:8080;
    proxy_read_timeout 90s;
}

It turns out that I didn't find how to inform the docker container which are the trusted proxies... And that's why shlink must not be accepting the "X-*" headers.

I tried to add the environment variable TRUSTED_PROXIES=172.20.0.100,127.0.0.1 but I was unsuccessful.

If I use the authoritative domain for shlink:8080 in the database, the APIs work and the error stops. However, the redirects start to fail.

I will continue investigating how I can resolve this and as soon as it is resolved I will post the solution here.

I think I misunderstood. I'm testing the project via the develop branch here, and when I simulated it, it tells me for which domain the short URL was not found.

In my post, it seems that the query param domain is ignored.
