ASA 5515X ASDM and SSH blocked

Hi guys.

We have a strange issue.

Periodically we lose remote access to both ASDM and SSH on our Cisco ASA 5515X Firewall.

The code version is 9.1(2) and the ASDM 7.1(3).

Normally I would assume it to be an ASDM issue and have solved similar by changing the version, however in this case SSH also stops to work.

The only workaround is to restart the firewall.

What makes this even more strange is that you cannot even open the web page for ASDM (eg, https://127.0.01).

It seems as if the entire SSL/Encryption layer has failed.

Has anyone experienced anything similar?

Or does anyone have any suggestions? Or alternative workarounds?

Many thanks.

Mike

Hi,

Hi,

We need to check the logs at the time of the issue.

Do you see anything in the logs when the issue is there ?

Also we need the output of sh asp table socket, show memory and show blocks.

Regards,

Aditya
