DNS-Settings not working
If the DNS settings are not recognized after adjusting them, this may be because the information is not yet available/updated worldwide. The change usually takes about 10 minutes, but can also take up to 24 hours, so please be patient.
If the change has not been applied even after the time mentioned, please note that some settings have to meet certain requirements. On the following (external) page you can find more information about this: https://support.google.com/domains/answer/3290350?hl=en&ref_topic=9018335
