Terraform Azure Application Insights failing with 401 on random resources after Azure AD issues

Question

I have a terraform library of different azure resources that were working fine the other day. Since the Azure AD failure I can't run a terraform plan anymore without random application insight resources failing due to 401 Unauthorized

Tried re-running az login but unfortunately still receiving issues.

Every plan is resulting in a different application insight resource throwing a 401.

Error: Error making Read request on AzureRM Application Insights '{resource-name}': insights.ComponentsClient#Get: Failure responding to request: StatusCode=401 -- Original Error: autorest/azure: Service returned an error. Status=401 Code="Unauthorized" Message="Unauthorized" InnerError={"diagnosticcontext":"1b8e2cf0-5fd5-4a0d-9b75-1093e63ecd18","time":"2020-09-29T16:32:34.3731943Z"}

Answer 1

Have you tried re-initializing your Terraform backend? Doing this sequence just resolved the issue for me.

az login terraform init terraform plan
