Warmer componet server misbehaving error

[chakreshkolluru]

I'm using kind kubernetes cluster. Flux was working fine initially. I kept my system in sleep mode and when i logged in back i'm getting error.

when i try to sync using below command:
fluxctl --k8s-fwd-ns=flux sync

getting following error:

Error: can not connect to git repository with URL ssh://git@github.com/chakreshkolluru/flux-get-started

Full error message: git clone --mirror: fatal: Could not read from remote repository., full output:
Cloning into bare repository '/tmp/flux-gitclone248425324'...
ssh: Could not resolve hostname github.com: Try again
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.

Run 'fluxctl sync --help' for usage.

Below are the logs of flux pod:

Can anyone help me in resolving this issue. I tried it two times by deleting and creating new kubernetes cluster using kind and getting same error.
