NimbostratusGTM 11.5.1 does not respond DNS queries anymore
Hello folks,
Yesterday, I upgraded a GTM from 11.2.1 to 11.5.1. It seemed that every configuration object was migrated from the old version to the new one, but the DNS name resolution failed. I have read the release notes of F5 and there is nothing about this kind of issues. The GTM is resolving a delegated subdomain which is located in the ISP provider's DNS. So. do I need to change something in the namedb or in the listener conf?
The traffic capture says: query response, server failure.
all comments and recommendations will be welcome.
Thanks in advance.

We add several features from 11.2.1 to 11.5.1 for DNS. first step would be to have a look to your DNS profile added to you VIP and see if options are correct.
check if all your WIP are green in the gui.
try to have look in /var/log/gtm and /var/log/ltm
omar05_132659I have reviewed the configuration of the UDP and DNS profiles. Nothing has changed.
There are just log files regarding to UP/DOWN gtm pools.
It is supposed that every upgrade must be smooth. I do not understand.
The WideIPs are in green state.
