401 forbidden on ASDM

nygenxny123 — Mon, 11 Mar 2019 17:24:42 GMT

I can get to the untrusted certificate on https....coming from my address 192.168.133.205..but i get denied

am i being denied by access list?..I dont see how since intital SSL begins..

these are the log from the ASA---10.11.24.11 is the ip of one of the contexts

Issue "sh asp table socket" and make sure it is listening on port 443.

If not just issue

conf t

no http server en

http server en

Then issue "sh asp table socket" and see if it is listening again and then launch asdm again.

Also issue "sh ver" and make sure an appropriate asdm image matching the OS is loaded.

I know this is an old message, I was hoping you were able to share if you fixed this issue as I think I am seeing the same problem and I am unable to find any information on the problem.

Kindly follow the Troubleshooting method, mentioned in this link:

https://supportforums.cisco.com/docs/DOC-15016

I feel that the connection is being terminated since ASDM image is missing in flash, or not mentioned in config.

Also please try accessing it with https:///admin and https:///

Hope this helps.

Hi Shrikant

Thank you for the link, I have tried accessing the context with the name at the end of the http string to no avail.

I am not to sure what the issue is here as I am able to access the ASA context from the outside interface always but get this error on the inside interface.

I am also not to sure about the certificate error as SSH always works and so does the ASDM on the outside interface.

Hi MJ,

I did some research on the error message you are getting, and I would like to suggest trying the following:

1. enable lower SSL versions on the browser as well.

2. try doing "no http server enable" followed by "http server enable 10000" and try accessing it using: https://ip_address:10000 and see if it works.

You can use any port other than 443. I randomly chose 10000.

3. if the ASA is in high availability, could you check if ASDM access to the standby unit works fine?

4. very last resort: reboot the current active device and check if this resolves the issue. (it might become standby if failover is present. make it active again.)

Is the inside interface shared among multiple contexts? If so does the interface have unique mac addresses in the various contexts?
