Error: Improperly Configured DNS Records

Solution: In this case narrowing down your issue can be of greater help, check whether you’re SPF, DKIM and MX records are properly configured or not.

Error: High TTL Values

Solution: Changes can be done to have low TTL values. But if your TTL values are low, your Query load will increase. If your server is able to handle the load, then there’s no problem.

Error: DDOS Attacks
