Hi I'm not very familiar with this product, taking over from somebody else.

Trying to connect to an existing SSL VPN setup, but the public IP address has changed (company moved). I've added new user, tried old users, they all work fine when I try the "SSL VPN" login in the backend.

I've changed the SSL port too, was 4443, made it back to 443. didn't change, the error messages are always the same, it seems the SSL handshake fails.

Here is the log from SecuExtender:

Thanks a lot for your help

    After a while, when I click on Connect on SecuEx 4.0.4, I get a Windows security prompt asking me to select a "Certificate" and I can choose in a list of Certificate by Adobe.

    Is there something to install on my windows 10 computer, prior to Connecting to the VPN ?

    Hi @aury,

    Can you take a screenshot on "Windows security prompt asking me to select a "Certificate" and I can choose in a list of Certificate by Adobe."?
