Since upgrading our firewalls from 10.2.2-h2 to either 10.2.3 or 10.2.3-h2, any DNS resolution from the management interface is failing. Attempting to ping an FQDN from the CLI results in "ping: cnn.com: System error". I confirmed that the DNS servers configured in Device -> Setup -> Services and the management interface settings in Device -> Setup -> Interfaces are correct and have not changed. We're using the same internal DNS server that we've been using for years and there are no issues with name resolution from other clients using those servers. is there any way to solve this?

Hey,
Did you manage to get to the root cause of this?
Still under research, but I could have something similar (10.1.9-h1 though), so poking around to see if this may be known issue.

Hello,
Besides checking the traffic logs, I would recommend opening a support case, or reading the release notes of higher versions.
