My domain is: www.com21.com
I ran this command: I add this domain to the my new server
It produced this output: Let’s Encrypt Verify error! DNS problem: NXDOMAIN looking up A for www.com21.com
My web server is (include version): Debian, 8
The operating system my web server runs on is (include version): Debian, 8
My hosting provider, if applicable, is: Kvmla.com
I am trying to move my website www.com21.com from the old server to a new one. Now, when I am trying to add the domain to the new server, it told me that “Let’s Encrypt Verify error! DNS problem: NXDOMAIN looking up A for www.com21.com”.
I am sure that the new DNS is working well, and I was trying ping this domain, it was working well all over the world. However, the problem is still there. I dont know how to deal with it.
Please help, thank you!
