Cisco ASA 9.16 with API 7.16.1 - 401 Unauthorized

jspencer_dragos — Wed, 22 Sep 2021 17:20:07 GMT

Hello,

I'm testing API access on 2 ASAs. One 9.12 and one 9.16. Both with API 7.16.1. Interacting with 9.12 ASA works as expected. When requesting a token from 9.16 I get a 401 Unauthorized. Trying to access the documentation at https://asa-ip/doc/ returns a repeated request to authenticate.

401 means Validation or authorization failed :

check the config and token again - the below document may help you :

I think this is the problem. Cisco Bug: CSCvy17365 - REST API Login Page Issue

Upgrading to 9.16.2 to see if that resolves the issue.
