The issue has been resolved after MS Case was opened. No error in Azure said MS, but other stuff started to work better as well after case was started. Could be due to the VM outage last week. No change in code but worked this morning without any errors and success in Terraform code. Case can be closed

Yeah, not configured that there has been changes on Microsoft side, but let's close it until it reappears :)
