<![CDATA[2.4.5 in testing, noticed domain override stopped working]]>Hi, I've been testing this new version, in a lab, and noticed that the domain override in DNS resolver stopped working.
It happens from time to time.

To solve, I've to edit the domain override and save it again.

This is just for information purposes to help the developers.
In case you need further details, or tests that I can perform to help, just let me know.

Version: 2.4.5.r.20200130.0307
Device: sg-3100

I' ll wait for the problem begin again, and I'll perform those lookups as you suggested, and will update this topic.

host -v blah. 127.0.0.1

and perhaps:

drill blah. @127.0.0.1

In either case, blah. should be the actual hostname you are trying to look up. Be sure to include the trailing dot.

I'm not aware of anything that would make only that one option fail.

I have a few Host Overrides that remains working, so the problem is only with the domain override.

The target server is within my LAN, directly connected to pfsense.

Didn't find any logs.

I've noticed the problem during LDAP authentication to pfsense.
Troubleshooted and found that it was working by IP.
Went to Diagnosis> DNS Lookup, and it wasn't resolving the domain.

So i've reapplied the DNS resolver domain override configuration, and it worked again.
This already happened twice, and I'm not sure what's is triggering it.

The problem is happening right now, I can perform tests if you like, packet captures, not sure what would be the best approach.

Nothing else? Other hosts resolve OK?

Is the target server for the domain override local to you, or remote (either over WAN or VPN)?

Any errors in the resolver log when it's failing?
