Cisco ASDM Issue

Chirag.Chirag — Tue, 09 Apr 2024 10:57:38 GMT

Hello Members,

I am working on setting-up a personal lab for Cisco ASA Firewall. I have successfully installed Cisco ASDM but can't access it, I am getting attached error when accessing the Cisco ASDM.

Any help or suggestion would be highly appreciated.

You could try changing the port that ASDM uses to something other than 443...for example you could do the following from CLI:

http server enable 4433

then try connecting.

Thanks for the link but he was trying to access the ASDM via Management Interface and I want to access the ASDM from the outside interface.

Also I don't see any satisfactory answer over that link, what he did is simply removed the SSL trust-point config on management interface.

As I said, change the port from the default tcp/443 to something else.

Also, post the output of show run all http

If the command http authentication-certificate <interface name> is present, remove it using no http authentication-certificate <interface name>
