I have a new customer and we installed a T80 with full DPI.
We have resolved most website issues, but their marketing department uses Facebook Messenger, and it shows a No internet connection error. I don't see any blocks in the traffic monitor, Facebook is not restricted in WebBlocker or App Control. Not sure what would be blocking this. I am thinking that it's like the Microsoft No Internet test, but I can't find that documented anywhere.
Thanks in advance
