warming during creating a cPanel account

Hello, I am receiving the following warning when creating cPanel accounts and consequently I am unable to renew the SSL certificates, due to the DNS resolution issue on the servers, highlighting that previously it was working fine and the domains were responding to the correct IP. Could someone tell me what's going on, please? Thank you in advance and sorry for pasting the whole warming here.

  If your resolvers are not working properly you'll prob. need to take that up with your hosting provider.  The only thing people on the forum would be able to suggest is changing the server to public DNS resolvers.

  Hello Madelino,
  
  This warning indicates that cPanel is having trouble resolving DNS records for the nameservers associated with the domain "verystrong.cv" during account creation. Also, it shows that cPanel's DNS resolver is getting a "SERVFAIL" response when trying to look up A records for ns.dns.cv and other nameservers. So ensure that the domain "verystrong.cv" has properly configured nameservers and verify nameserver's A record is properly resolving to correct servers. 

  Thank you

  Regards,

  Hi,

   

  This type of error is often caused by restrictive firewall settings. To help narrow down the issue, you can run the following command, which performs a DNS lookup in the same way cPanel does during account creation:

   

  /scripts/cpdig example.domain.tld A --verbose

  Note: Replace example.domain.tld with the domain name mentioned in the error

  Executing this command from your server will show which IP addresses are failing to respond during the DNS lookup process. This information can help pinpoint where the connection is being blocked, allowing you to adjust your firewall settings accordingly.
