The were problems responding to a post today.
The webpage was refreshed > same Azure block
The webpage was reopened by clicking on the email link > same Azure block
Pasting only: https://docs.microsoft.com/answers/answers/398511/post.html into the thread worked.
Then multiple edits were performed.
This was the thread that had had the Azure blocks:
WAF v2 has determined your request exceeded the normal web request and has blocked your request.
Go to Microsoft Q&A
How was the Azure block designed to work?
How come it had false positives?
How do you troubleshoot the false positive?
What do you do in case it happens again?
