Hi Zargham,

I belive it is sending the client hello with SSLv2 as the version. This particular version is discontinued. Try to upgrade the java version and the ASDM version.

Also try to access the ASA via https using the Mozilla browser and see if you are getting any error message.

Thanks,

Dear All,

Hi,

Ensure you are using recommended ASDM version for your ASA OS version.

Refer following link to know more about ASA and ASDM compatibility:
