My customer have a problem with their SSL VPN Connection both Webvpn or Annyconnect connection.
We're trying to connect using webvpn, the login page is not come up and take long response while loading. I've got the capture from wireshark, between the success connection and the failed one for comparisson.
Here is capture for succcess connection:
And this one for failed connection:
As we've seen in the failure capture, there is no Certificate & Server Hello Done during SSL Handshake between ASA to the client. Why it can be happened?
It's seems ASA can not send complete packet to the client ? Anybody have same issue with us?
