Hello, I am working on a project where I need to host several websites on the same server, for this I turned to traefik, I managed to configure everything correctly, I can access my sites on my different subdomains. However I have an error when I want to communicate between these different sites, I have 3 services that run on my traefik, an API, a main website and an admin website. The admin website and the main website need to make requests on the API but it's unfortunately impossible, both sites return a 500 error with a timeout as below:

```auto

I also try to make a request from the admin container to the api container as below, but I get the same error...
