Hi Wonderful People of This Community

Yet another ASDM issue. We can't seem to figure it out. Please help! We can't access the https webpage nor via ASDM (obviously).

ANSWER

Ah yes that was it. Thanks. This was a really old RMA firewall. After activating the new key we also had to issue this command:

ssl encryption 3des-sha1 aes128-sha1 rc4-md5 rc4-sha1

Thanks again.
