Hello
We have Sophos UTM running FW 9.502-4. We use Web Filtering in Standard Mode and AD SSO. HTTPS is set to Decrypt & Scan.
We have some employees who want to use Grammarly, but this is being blocked. Using the Grammarly diagnostic test, it seems that the WebSockets test is failing. I've next to no knowledge of WebSockets, some basic Googling reveals that UTM does not support WebSockets and the problem is related to it using Port 80/443.
Normally, and like this forum post, I create a web filtering exception so that SSL is not scanned. However even with the filtering exception in place we still get the WebSockets fail.
I have watched the Web Proection Live Log and cannot see any traffic being blocked for Grammarly. I have also searched Web Protection logs for blocked traffic and Grammarly is not in the list.
I know it's the filter, since if I use a computer/account exluded from web filtering then Grammarly passes fine.
I am doing something wrong, or does anyone have any other suggestions?
Many thanks
