Self-hosted runners not available

Hi Team,

I am working on the project ‘k0s’ and trying to add tests for ARM64 in GitHub Actions using self-hosted runners for ARM64.

However, it seems that the runners are not available online. I am getting the below error logs on the CI:

This request was automatically failed because there were no enabled runners online to process the request for more than 1 days. 

Jobs waited for runners to get scheduled for more than a day, and then got failed.
Below is how I configured self-hosted runner for ARM64 tests:

  runs-on: [self-hosted, linux, ARM64] 

I have tried re-running jobs in the hope of runners getting available, but no luck.

Can you please provide some pointers on this? Kindly ping if you need more information from my end.
