AUTHOR: MR. TURRITOPSIS DOHRNII TEO EN MING COUNTRY: SINGAPORE DATE: 3RD OCTOBER 2018 WEDNESDAY TIME: 9:28 PM SINGAPORE TIME GMT+8 Document Version: 1810.01 Error Symptoms: Added DNS host record to cPanel virtual server and synchronized to all name servers but it cannot be queried. Problem was described at https://forums.cpanel.net/threads/dns-records-are-not-synchronizing.638673/ This thread was started by Teo En Ming. Cause: My DNS Cluster was configured correctly and also synchronizing correctly as well. However, there are THREE (3) zone files which contain the same domain name teo-en-ming-corp.com, which causes great confusion for the BIND DNS server. As a result, DNS host record which is added and synchronized successfully could not be queried. There should be only one zone file for one domain name.

Click DNS Functions > Delete a DNS Zone 2. Choose a zone which contain teo-en-ming-corp.com to delete. 3. Click Delete. 4.

Chapter 3 Editing DNS Zone and Adding Mandatory DNS Host Records ================================================================ 1. Click DNS Functions > Edit DNS Zone 2. Choose teo-en-ming-corp.com 3. Click Edit. 4. The following steps are to be performed under the section Add New Entries Below this Line 5. Key in store, Select A record, and key in 18.223.148.223. 6.

The main cPanel server will automatically synchronize this DNS zone and all DNS records to all name servers. Chapter 4 How Your Final BIND DNS Zone File Will Look Like ========================================================== ; cPanel first:74.0.8 (update_time):1538570173 Cpanel::ZoneFile::VERSION:1.3 hostname:ns1.teo-en-ming-corp.com latest:74.0.6 ; Zone file for teo-en-ming-corp.com $TTL 14400 teo-en-ming-corp.com. 86400 IN SOA ns1.teo-en-ming-corp.com. teo.en.ming.gmail.com.
