Hi there. My objective is to run our application in Github codespaces. This works great, but I can’t connect to the Mongodb instance, from my local machine with for example MongoDB Compass.
docker-compose.yml

# Use -bullseye variants on local arm64/Apple Silicon.
VARIANT: '16'

The app itself can connect to the Mongodb instance, without issues. Port forwarding is made public like here:
However when I try to connect from MongoDB Compass running locally with:
mongodb://<code-space-name>-4q75x555hj7rv-27017.githubpreview.dev:80
I always get:

Would be so thankful for any points in the right direction
