SOLVED Hostname not resolving?

[webtipster]

Problem with the hostname not resolving at all. Not sure what has happened overnight but both servers do not respond to their hostname ie. WHM/cPanel is not accessible.

Server is UP and all services are running. However the server hostname cannot be accessed via URL at all.

Ran a DNS Stuff DNS check and everything resolves fine.

Checked /etc/sysconfig/network and hostname is listed.
Checked domain.db for the domain and everything looks fine ns1,ns2 etc are there.

Not sure what else to check?

Hello,

Can you successfully ping or use the "host" command with the hostname from your workstation? Do you notice any output to /usr/local/apache/logs/error_log when attempting to open the hostname as a URL in a web browser?

Thank you.

Hi Michael,

Thank you on your prompt reply.

Ping returns: Ping request could not find host xxx.domainname.net. Please check the name and try again.
URL: This site can’t be reached. xxx.domainname.net’s server DNS address could not be found.

If I ping just the domain name (not hostname) I get successful reply and can access the URL through browser.

Any ideas?

Thanks in advance.

Just a quick update forgot to check the host commands from the ssh:

If I run host -t CNAME xxx.domainname.net I get Host xxx.domainname.net not found: 3(NXDomain)
If I run host xxx, I get Host xxx not found: 3(NXDomain)

Thank you.

Ok went back in and fixed it.

Deleted the DNS zone for domainname.net, logged in using server IP to WHM and re-created the DNS zone for domainname.net, double checked that hostname was correct, hostname IP was assigned, re-assigned it again, checked the correct A entries are there, cleaned DNS zones, synced DNS records, and voila back in in business.

Thank you for posting the steps you took to solve this. They are, rewritten:

1. Deleted the DNS zone for domainname.net,
2. Logged in using server IP to WHM,
3. Re-created the DNS zone for domainname.net,
4. Double checked that hostname was correct, hostname IP was assigned,
5. Re-assigned it again,
6. Checked the correct A entries are there,
7. Cleaned DNS zones,
8. Synced DNS records, and
9. Voila back in in business

Would you be able to expound on where or how steps 2 & 5-8 were accomplished?

Hello @David Colter,

Logged in using server IP to WHM,

This simply implies accessing Web Host Manager directly over the IP address. EX:

https://$server-IP:2087

• Re-assigned it again,

• Checked the correct A entries are there,

• Cleaned DNS zones,

• Synced DNS records, and

DNS Zone modifications are possible via "WHM >> Edit DNS Zone". If you utilize a DNS cluster, you can force a synchronization of the changes via "WHM >> Synchronize DNS Records".

Thank you.
