GoogleApps Server reverse lookup

MariaDB Configuration Management CentOS

Hi,
I have a droplet with mariaDB installed properly and running ok, however today I got a lot of errors of a piece of code that I have in Google Apps Script, looking in server logs I found that iptables is correctly configures as is listed here but in mariaDB I got a lot of errors that I never had before. The errors are:
[Warning] IP address 'X.X.X.X' could not be resolved: Name or service not known
Based in a configuration in mariaDB a succesful reverse dns lookup is required in order to get access to DB, however in the past the IP segments listed by google to be whitelisted were correctly, What is the reason of the recent change? I didn't make any change in my host.conf recently, so I suppose this is a problem on your side.
I have changed the mariaDB conf to not required dns lookup , because I have a restricted rule access in Iptables and that's give me enough protection for now, but I have planes in the future to change it, so I will need your help.

Greetings.

There is nothing on our end that has changed recently that would be related to this. You can set up a PTR (reverse DNS) record for your droplet by ensuring that the name you've given the droplet is a proper domain or subdomain name. The PTR is created automatically on our system. If you did not have a properly formatted domain as the name of your droplet there may have been an old PTR out there for the IP that has expired or was removed as no longer correct.
