Applicable to:
- Plesk for Linux
- Plesk for Windows
Symptoms
-
WWW alias, website's subdomain or webmail URL that are hosted in Plesk cannot be opened with the following error:
CONFIG_TEXT: This site can’t be reached
DNS_PROBE_FINISHED_NXDOMAINOR
CONFIG_TEXT: This site can’t be reached
ERR_NAME_NOT_RESOLVED -
The main domain
example.comis accessible without any issues. -
The DNS checker https://mxtoolbox.com/ shows that DNS record for www.example.com, webmail.example.com or one.example.com is not published:
Cause
Missing DNS record (type CNAME) for www.example.com or (type A) for subdomain one.example.com or webmail webmail.example.com.
Resolution
Verify what name servers are used to serve DNS for example.com:
- Go to the online NS record checker (for instance this one: Online tool for NS server check) and find what name servers are used for example.com;
- Check if the NS servers are the same as in the Domains > example.com > DNS Settings (NS records). If they are, then DNS service is managed by Plesk.
If different name servers are used, or the option Domains > example.com > DNS Settings is absent, 3rd party name server provider is used (i.e. DNS provider).
-
Go to Domains > example.com > DNS Settings > click Add Record
-
For www.example.com, add a CNAME record:
For one.example.com or webmail.example.com, add an A-record:
-
Click the OK button.
Contact DNS provider (registrar side) to create required CNAME or A-record.

Before taking action based on the provided information, I appreciate to have an assistance regarding the issue that i am dealing with.
I have my domain running on another server with office webmail. In Plesk I am trying to work with A record subdomain and initialising webmail for it without interacting my domain. But the webmail page is empty. Although in log file it says that the email is sent by php but no delivery from the other end.
So is this possible to used (Domains > example.com > DNS Settings is absent, 3-d party name server) without causing any problem for my domain and have the webmail running for subdomain in Plesk ?!
Hello, I have the same problems. Had to disable DNSSEC in the Registrar's domain settings, and remove from all dns servers the wrong subdomain zone, then it started to work. According to my opinion subdomains - created as zones like in plesk obsidian currently- do not work together with DNSSEC. If DNSSEC is activated, Plesk should create just A and AAAA Records in the DNSSECed Domain, and not create a subdomain zone.
