Stack Formbricks with traefik, 404 error, using docker and portainer

Question

I have a docker swarm and portainer installation.

I've created a formbricks stack, the image comes up normally, the container is created and the database is also created.

Everything seems to work fine, but when I access it through my domain using traefik, I get a 404 error.

And that's my stack:

I've tried a few ways and I can't figure it out.

I've tried putting WEBAPP_URL="https://test.com, but it doesn't work.
