Edge browser very slow/timeouts when using SSL Forward Proxy on Firewall RRS feed

  • Question

  • Hello,

    We have a problem at one of our new locations with the Edge Browser when using SSL Forward Proxy (Palo Alto Firewall).

    The problem is as following: When we activate the SSL Forward Proxy, the Edge browser takes very long and sometimes even disconnects when trying to open a normal webpage over TLSv2. Chrome, Mozilla & Internet explorer are OK. Certificates are also trusted and there are no GPO rules for the Edge browser.

    I made a packet capture and noticed following: The server key exchange packet comes in, and then the client takes a long time to respond with the client key exchange (~10seconds). So there seems to be a problem there.

    I know that this is not a network forum, but did any of you have the same problem with the Edge Browser? Or anything similar?

    Sorry for my bad english..

    Thanks and regards
