Yes, @uhlhosting. That is the place you need to set port to 8080.

The 404 page IS the application running correctly.

Your next step I believe is to log into your server via SSH and find the container to run the command to generate the API key that you will use to begin using this application, as outlined in the official docs for this application.

Some applications will generate a new API key on the first run and reveal it early in the logs but this application is not one of them. They designed it so you have to run a command against a running container. Sadly, the name is not predictable so you have to find the container name by running another command.

Once you SSH into your machine running Caprover, run docker ps ls | grep shlink to find the container name.

Then run docker exec -it my_shlink shlink api-key:generate, replacing "my_shlink" with the unique name of your container, as outlined in this document: https://shlink.io/documentation/install-docker-image/.

Like so:

@maietta thanks for the explaining, I managed to generate the API key too, yet still when I add it in the web ui app, it gives error.

I think I got it working in app.shlink.to, would be nice to add this too in caprover.
