[Bug]: Codeberg repo failed to push image to docker registry.

Description and Error Message

So i tried out CodeBerg as Git. Now i have 3 servers (i have more but 3 are for this bug):

• Coolify Frontend
• Coolify Docker Build
• Coolify Kelvin node

I've created a access token on CodeBerg with read/write on every permission. On every server i used docker login codeberg.org with the access token.

On all three servers i ran the following in the CLI to test the Docker registry:

• docker pull alpine:latest
• docker tag alpine:latest codeberg.org/heapreaper/rc-garage-nl:test
• docker push codeberg.org/heapreaper/rc-garage-nl:test Which ran succesfully on all three servers.

But when i deploy in Coolify, i get:
