Hi,
I'm using Sophos Endpoint Security and Control 10.0, and unfortunately it blocks the HTTP or WebSocket Connection between the Firefox Addon KeeFox and the Password Manager KeePass. When I disable Sophos Web Protection its working, when Web Protection is enabled KeeFox is not able to connect. The issue is described in the KeeFox Forum aswell: https://discussions.zoho.com/keefox/topic/keefox-doesn-t-connect-to-keepass
The KeeFox Developer is describing the connection process like this:
KeeFox and KPRPC communicate using a websocket on 12546 but that socket is usually only established following a "successful" HTTP connection to the same port (for technical websocket implementation reasons). Where "successful" means that the connection to the port was closed in a way that indicates KPRPC is listening for web socket connections. That's not fool-proof, hence the recent addition of a fallback where the HTTP connection success is ignored and the web socket connection is attempted every 80ish seconds anyway
In my opinion Sophos Web Protection shouldn't block this kind of connections....
best regards
