Hi forum,
I´ve the same problem on two computers. With a trial version of "internet security" and with free antivirus. If I click on the button to add add the installation to my existing avast-account, the window seems to be frozen.
I´ve analyzed the communication with wireshark on both sides (avm-dsl router and PC). Its always the same. After the session setup (handshake), the client sends with the tcp-packet 4 a pair-check to the server (unencrypted?). With the next three packets the server terminates the session. Thats it.
For me it looks like a BUG in the software, due to the https session. In the attachment there is my monitored session shown.
I think, we have to wait for a bugfix...
kind regards
Norbert
