Issue First trial with SSL certificate / Authorization for the domain failed.

[eric91611116]

Dear all,
I am new here. Recently I bought a domain etfdp.com at godaddy.com. Then I subscribed a hosting service at AspHostPortal.
At godaddy side, DNS settings:
I have added a A record with an IP 23.111.13.151 pointing to AspHostPortal.
At AspHostPortal, I uploaded my web application. I can access it.
Since https SSL is a must, I tried to use the "Let's Encrypt SSL/TLS certificate". I got the below error msg

Could not issue an SSL/TLS certificate for etfdp.com
Details
Could not issue a Let's Encrypt SSL/TLS certificate for etfdp.com. Authorization for the domain failed.
Details
Invalid response from https://acme-v02.api.letsencrypt.org/acme/authz-v3/238181962037.
Details:
Type: urn:ietfarams:acme:error:dns
Status: 400
Detail: DNS problem: NXDOMAIN looking up TXT for _acme-challenge.etfdp.com - check that a DNS record exists for this domain

I appreciate it much for anyone who can share your advice and experience.

Thanks,
Eric

The TXT record in the domain is required if you try to create a wildcard SSL certificate. If you do not need a wildcard (which is most often the case for many users), simply issue a normal SSL certificate. Then the TXT record will not be required and the tokens can be exchanged with Let's Encrypt right away.
