FAQ-What Do I Do When the Message "NO_PROPOSAL_CHOSEN" Is Displayed During Debugging?

Publication Date:  2019-01-25 Views:  384 Downloads:  0

Issue Description

What do I do when the message "NO_PROPOSAL_CHOSEN" is displayed during debugging?

Solution

This problem occurs because no matching security proposal is available. In phase 1, check whether an IKE proposal matches that of the peer end. In phase 2, check whether the parameters of the applied IPSec policies, protocols of referenced IPSec proposals, encryption algorithms, and authentication algorithms are matched on the interfaces of the two negotiating devices.
