Hello.
Since 2 days ago, I received this email every day.

I force the update with:
Code:
/scripts/upcp --force
And again, have the same error.

I use:
Code:
awk '$4=="E"' /var/cpanel/updatelogs/update.1581671535.log
Is the last log, and I have this result:
Code:
[[email protected] ~]# awk '$4=="E"' /var/cpanel/updatelogs/update.1581671535.log
[2020-02-14 10:14:14 +0100] E    [/usr/local/cpanel/scripts/check_unreliable_resolvers] The “/usr/local/cpanel/scripts/check_unreliable_resolvers --notify” command (process 4790) reported error number 1 when it ended.
[2020-02-14 10:14:18 +0100] E Post Maintenance ended, however it did not exit cleanly (256). The following events were logged: "scripts/check_unreliable_resolvers". Please check thelogs for an indication of what happened
I dón't know exactly what are the problem...

Also indicate that, when start this problem, and when execute this scripts/upcp and when received this email with this error, also I received other mail with:

Partial DNS resolver failure

With this:

Hello @cPanelLauren !

Yes, you indicate the problem and the solution...yes, the problem was with the IPv6 address that's failing with resolvers.

I remove the IPv6 from resolver configuration, after this, I execute:
Code:
/scripts/check_unreliable_resolvers
The result are: OK

After this, I execute:
Code:
/scripts/upcp --force
Any error (any mail with error) all ok, fixed the problem.

Then, the problem is with IPv6 of resolver, I can remove for ever or contact with my provider for comunicate this for if they have problem with this ip and change or remove? This ip's, of resolve are of my host, I have differents VPS with this provider and in all VPS this ip's arre differents.
This IPv6 are in Tertiary Resolver (optional), the first and the second are IPv4.

Thanks and regards!

Yep, exactly and if you wanted to add an alternate tertiary resolver until they get back to you, you can add one from google or Cloudflare resolvers though it's not necessary to have the third.
