Website is not accessible: This site can’t be reached

Applicable to:

  • Plesk for Linux
  • Plesk for Windows

Symptoms

Website is not accessible:

  • Firefox: Server not found
  • Opera: Could not locate remote server
  • Internet Explorer: Internet Explorer cannot display the webpage or shows This page can’t be displayed message
  • Google Chrome: This site can’t be reached

Whois command does not return information about the DNS zone:

# whois example.com
[Querying whois.verisign-grs.com]
[whois.verisign-grs.com: Temporary failure in name resolution]
[Unable to connect to remote host]

DNS zone authority server is not Plesk server:

# dig  SOA example.com

; <<>> DiG 9.8.2rc1-RedHat-9.8.2-0.62.rc1.el6_9.2 <<>> SOA example.com
;; global options: +cmd
;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: NXDOMAIN, id: 39612
;; flags: qr rd ra; QUERY: 1, ANSWER: 0, AUTHORITY: 1, ADDITIONAL: 0

;; QUESTION SECTION:
;example.com.                IN      SOA

;; AUTHORITY SECTION:
com.                    60      IN      SOA    a.gtld-servers.net. nstld.verisign-grs.com. 1501196004 1800 900 604800 86400

The same request to Plesk-hosted DNS server shows that it is the authority server for this zone:

# dig @plesk_ip_address SOA example.com

; <<>> DiG 9.8.2rc1-RedHat-9.8.2-0.62.rc1.el6_9.2 <<>> @plesk_ip_address SOA example.com 

;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 6464
;; flags: qr aa rd; QUERY: 1, ANSWER: 1, AUTHORITY: 0, ADDITIONAL: 1
;; WARNING: recursion requested but not available
;; QUESTION SECTION:
;example.com. IN SOA
;; ANSWER SECTION:
example.com. 86400 IN SOA ns1.example.com. shaq912.yahoo.com. 1498796889 300 3600 604800 300
;; ADDITIONAL SECTION:
ns1.example.com. 86400 IN A plesk_ip_address 

Cause

DNS name cannot be resolved dur to the zone misconfiguration on the domain registrar company's side.

Resolution

Please contact the domain registrar company regarding the issue
