Expected Behavior
When you run the ddev start command, you should see the site via the domain name
Actual Behavior
Randomly, when we launch a project, we get a "404 page not found" error when we access it via the domain (the site is displayed via the ip).
Looking at the logs with the command docker logs -f ddev-router, we see the following error:
‘ERR github.com/traefik/traefik/v3/pkg/provider/aggregator/aggregator.go:206 > Cannot start the provider *file.Provider error=’error creating file watcher: too many open files’.
We encounter this error on Ubuntu 22.04 and 24.04 and ddev on 1.23.4
