Describe the Bug

Hi,
I tried to install via Docker Compose with exact config from here: https://docs.digpangolin.com/self-host/manual/docker-compose, but I get "Network Error" on the initial setup page.
I do not see any error in the containers logs.
I have a Debian 13 VPS.
Thanks for your help :)

@Ultimatum22 commented on GitHub (Oct 20, 2025):

I have the same issue. Log is on debug but nothing is shown. What I do see with F12 in the console in the browser is this while I try to logon:
Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at https://example.com/api/v1/auth/set-server-admin. (Reason: CORS request did not succeed). Status code: (null).

I have a real working domain in my case.

I haven't found which combination works yet.

To be clear, I only have pangolin and traefik running. I don't need gebril yet right to first get the dashboard up? I want to take it step by step.

Okay, I made a lot of shortcuts which I shouldn't. Updating the Traefik dynamic routes where missing on my end. @aleduc-cyb can you try my steps and see if that helps you?

Ok I got the same error as you with Firefox. What is actually weird is that the URL in the CORS error message is "pangolin.mydomain.ovh.com/api/v1/auth/set-server-admin". I double checked my traefik configs and it seems I did not input anything like "mydomain.ovh.com" anywhere.

To be clear: the URL should be "pangolin.mydomain.ovh/api/v1/auth/set-server-admin", without the .com.

I used pangolin 1.9.4 image, and I do not have the problem. Problem is there with 1.10.0 and latest though (all tested with traefik 3.4.4).

@oschwartz10612 commented on GitHub (Oct 26, 2025):

Hey everyone. This sounds like a cors issue. Not sure yet why there would be issues on the latest version. Can you check your config and make sure there is something like this in the server section? The domain should be your domain you are using.

server:
    secret: "Ti21lrb0UF62y9i68IbSoPZniQifoFkh"
    cors:
        origins: ["https://p.fosrl.io"]
        methods: ["GET", "POST", "PUT", "DELETE", "PATCH"]
        allowed_headers: ["X-CSRF-Token", "Content-Type"]
        credentials: false

OK my dumb ass forgot to check the pangolin config file, I indeed had a typo :)
Thanks a lot for your help.
