Server Monitoring of User-ID agent set-up shows Authentication failed /Connection refused error

L3 Networker

We have over 80+ firewalls in our environment, all of them of version 10.1.6.-h6 , we are using Kerberos profile in the user-id agent set-up and every server monitor status seems connected. Except for the firewall which is with PAN-OS version 10.2.3.-h4, even after using the same parameters.

getting below error:

Server monitor HOSTNAMEDP(vsys1): connection failed, HTTP code 401, (null)

 

Kindly suggest us on above condition.

Hi @Sujanya ,

 

That error is too general and requires additional debugging.

 

I'd make sure the clock is synced under the same NTP server everywhere.

Also enable debug logging:

debug user-id on debug
debug user-id set userid servermonitor

Also capture krb5 and http traffic at the time of the issue

1) kerberos traffic is between fw and kdc server on port 88.
2) http traffic is between fw and server monitor server on port 5985.

 

You might want to grab all this info + a tech support file and send it over to TAC for analysis.

 

Kind regards,

-Kiwi.
