What's your current start command and where is it set?

command: gunicorn backend.wsgi, set inside of my docker.yaml, should this be in a procfile instead? wasn't sure if that was necessary or not

docker.yaml is in no way applicable for the Railway platform, where else have you set a start command?

only in the .yml currently, I had a procfile using the same command but was just trying to figure out docker so went with just that, so should I get rid of that and just set it in the procfile?

A Procfile is a heroku thing, while Railway does support them, it's best to use a railway.json file instead, here's an example -

https://github.com/railwayapp-templates/flask/blob/main/railway.json

ok, switched over to the railway.json, seems to build/start, but still getting the 503? attached logs

Both your logs look good, perhaps you had checked the link before the new deployment went live so you where still shown the old error page, would you still be experiencing this issue?
