Hey there,
I have a custom error rule that is used to display a custom error asset maintenance mode page. It's worked previously, but now it seems like it's not even being evaluated when it's active? I can see that a transform rule for HTTP response headers is matching in the Trace view, which would take place after the custom error rule in the traffic sequence. To help me debug, I've set the condition for the maintenance rule to all requests, and I still can't see the maintenance page.
Am I missing something? Has something changed recently?
Thanks
