Unable to launch ASDM from x.x.x.x:

java.lang.IllegalArgumentException: SSLv2Hello cannot be enabled unless at least one other supported version is also enabled

I installed ASDM after several attempts. for this i install SUN jre 5 and then i successfully install it but after installation i face new error which is mentioned above. details are :

OS : Windows 7

i install :

ASDM ver : asdm-602

jre-7u79-windows-i586

jdk-7u79-windows-x64

sun java version 5.0

previousy it was working fine with my ASA 5510 but my laptop crashes and i rebuild my system but this error is appearing....

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,

Hi,

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

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