Recently I started to play with Flux. I have installed it in an AKS cluster and deploying components from Azure DevOps. But I got a noobish issue when I try Image Update future, in the events I see when a new image was pushed to docker registry (so this bit works fine) but it complains with error gitrepository unable to clone 'https://dev.azure.com/.../REPORTING', error: SSL error: 0xffffffff - UNKNOWN ERROR CODE (0001) . Then imageupdateautomation says no updates I suspect that the issue is not in clone, because I am reading and deploying HealmReleases from the same gitrepo. I would be grateful, if anyone could point me what's miss configured.

apiVersion: source.toolkit.fluxcd.io/v1beta1
kind: GitRepository
metadata:
  name: reporting
  namespace: lsng
spec:
  interval: 1m
  url: https://dev.azure.com/.../_git/REPORTING

And bellow line is added in reporting repo on the deployment: 
image: "{{ $current.image.repository }}:{{ $global.image.tag }}" # {"$imagepolicy": "policy:ts-policy"}
