AMP blocks PDF file download without logging to security center
since last Monday afternoon CEST we encounter an issue with AMP. All our worldwide MX devices with AMP enabled are blocking the download of PDF files that are located in our internal networks. As soon as a client is not in the same subnet as the originating server, downloading and displaying of PDFs is not possible. When disabling AMP it is working fine. Strangely it is working fine from the internet!
So we checked the event logs of some of the networks in question. But there is no entry of any AMP action that would give us a chance to to whiteliste the filetype.
We are running on FW 15.42.1 and 15.42.3 already before this issue occured.
Our IT guys mostly around Europe started to report the issue on Monday at approx 2:30 pm CEST.
We have opened and case for this.
I wanted to check out if anyone else is having this as well.
