DNS problem: NXDOMAIN looking up A for <domain-name>

I’m getting the following error:
DNS Problem NXDOMAIN looking up A for domain :

our system use 1 tomcat server in local (only Lan network can access) then configure haproxy to get domain-name on this tomcat server.
use >haproxy >tomcat apache server.
Do you have any suggestions as to the cause of this error…?


This domain name is still available for purchase (if the WHOIS works correctly).
If you want to obtain a certificate for a domain, the domain must be registered and publicly resolveable.

Thank you

thank you for your advice,
in my screen, I just share a test VM server, because the live server with other domain did register and publicly resolvable. but I worry if I do it same on the live server using HTTP may have error same.

I think it's worth trying.
If that domain is publicly resolveable, reachable and serve content that it should / required to serve, there should be no issue getting a certificate for that domain.

However, if there's any issue, you can post it to this forum and we are here to help. :smile:

Thank you

thank you so much, I will try :slight_smile: if have any issue I will post here …!
