I have a question about the COA server key.

[CCC3]

I am trying to use c9800 (17.6.4) and ise 2.7 as cwa.

Web page redirection happens normally.

However, there is no internet connection after that.

Looking at the live log
'11213 No response received from Network Access Device after sending a Dynamic Authorization request'
An error message appears.

I know that the error is related to COA.

When entering the COA Server key on the 9800, is there something that needs to be matched with this elsewhere?
