When trying to open website, the following error appears:
The page cannot be displayed
Website can not be found
Status of the domain in OA is
Domain name cannot be resolved.
Please follow the steps listed below to find where the problem is. Let's use the "domain.tld" domain as an example.
First, domain nameservers must be found. This can be done with the following command:
~ whois domain.tld ...... Nameserver Information: Nameserver: a.iana-servers.net. IP Address: 188.8.131.52 Nameserver: b.iana-servers.net. IP Address: 184.108.40.206 .....
If there are no records about nameservers in the "whois" information, you should set them in the registrar - contact registrar to do it.
Try to resolve the domain through its nameservers with the
nslookupcommand. The output should appear as follows:
~ host domain.tld 220.127.116.11 Using domain server: Name: 18.104.22.168 Address: 22.214.171.124#53 Aliases: domain.tld has address 126.96.36.199
If an error "no servers could be reached" appears:
~ host domain.tld 188.8.131.52 ;; connection timed out; no servers could be reached
It means that
namedservice is not running on the nameserver, or that port 53 is blocked by a firewall.
If you get an empty answer or "not found" reply:
~ host domain.tld 184.108.40.206 Using domain server: Name: 220.127.116.11 Address: 18.104.22.168#53 Aliases: Host domain.tld not found: 3(NXDOMAIN)
It means that the domain you are trying to resolve doesn't exist on this nameserver. Please add it to the appropriate zone.
The "(SERVFAIL)" error:
~ host domain.tld 22.214.171.124 Using domain server: Name: 126.96.36.199 Address: 188.8.131.52#53 Aliases: Host domain.tld not found: 2(SERVFAIL)
Indicates that the zone for the domain contains errors. Try to restart
# /etc/init.d/named restart
and look in
/var/log/messagesfor the "domain.tld" zone-loading errors.
Try to use dig with trace output:
# dig +trace domain.tld
For Plesk: if you are able to find NS server in trace output from server machine and whois is showing correct output try to update DNS record for this domain:
/usr/local/psa/admin/bin/dnsmng --update domain.tld
