Secondary Resolver Configuration with errors

[fmosse]

Hi,

Yesterday and today I received this email about one dedicated server with WHM

"Maintenance ended; however, it did not exit cleanly (256). The following events were logged: “scripts/check_unreliable_resolvers”. Review the update logs to determine why the update failed."

And also another with this:

I entered to Home »Networking Setup »Resolver Configuration
and I have:

Primary Resolver 8.8.8.8
Secondary Resolver 8.4.4.4
Tertiary Resolver (optional) 4.2.2.1

So I think that the Secondary Resolver has a problem.

What should I do?

Thanks,
Francisco

Yea, I agree, the secondary resolver is incorrect for Google's Resolvers. It should be 8.8.4.4 not 8.4.4.4 - Get Started | Public DNS | Google Developers

Personally I prefer CloudFlare's right now (which they introduced on April 1st 2018) - it's significantly faster - Introducing DNS Resolver, 1.1.1.1 (not a joke)
