global-default-backend does not find services in K8S

[prg3]

Do you want to request a feature or report a bug?

Bug

What did you do?

Added service and ingress as below configuration.

What did you expect to see?

On the dashboard I would expect to see the "global-default-backend" to show green and have the backend services.

What did you see instead?

global-default-backend shows red and no services attached.

Output of traefik version: (What version of Traefik are you using?)

1.7.8

What is your environment & configuration (arguments, toml, provider, platform, ...)?

Hi! I'm Træfiker 🤖 the bot in charge of communication regulation.

Thanks for your interest in Traefik!

We dedicate the issue tracker to bug reports and feature requests only. My advanced AI tells me this one is neither of them.

I encourage your to seek community support: join our Slack workspace and reach out to us on the #support channel.

Another option is to use Stack Overflow and tag your question traefik.

You can of course double check Traefik's documentation 😅

Building off of the patch branch solves the problem on my test system.
