When trying view logs in Application Insights and Log Analytics workspace, we are getting the following error:
Failed to retrieve schema. Please try to refresh the page.
We have experienced a connection issue while retrieving data. This is usually an indication that the network is down or a firewall or browser extension (such as an ad blocker) is mistakenly preventing access. Connection Error.
When looking at the Service Issue in the portal, there are no issues.
We are using east us location.
As far as I know, nothing has changed.
In the console log I see this error:
Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at https://api.loganalytics.io/v1
CORS request did not succeed). Status code: (null)
