After getting help from @rfay in the ddev discord channel we were able to pin point the issues.

I'm using Linux - PopOs which is based in Ubuntu. I had initially installed using the script instead of using the package manager apt . So I uninstalled ddev and mkcert using the following commands:

sudo rm /usr/local/bin/ddev*

sudo rm /usr/local/bin/mkcert

I then followed the steps of installing through Debian/Ubuntu. Steps can be seen here.

After that, I checked the logs for traefik using the following commands:

ddev poweroff
ddev start
docker logs ddev-router

Which returned the following error message:

2025-08-26T16:37:30-03:00 ERR Cannot start the provider *file.Provider error="error adding file watcher: no space left on device"

I then followed the troubleshooting steps

By changing the max_user_watches then I was able to resolve the domain for my project.
