To fix these errors, please make sure that your domain name was
entered correctly and the DNS A/AAAA record(s) for that domain
contain(s) the right IP address.
My web server is (include version): Apache/2.4.29
The operating system my web server runs on is (include version): Ubuntu 18.04
My hosting provider, if applicable, is: IONOS (www.ionos.fr)
I can login to a root shell on my machine (yes or no, or I don't know): Yes
I'm using a control panel to manage my site (no, or provide the name and version of the control panel):
Yes, for my domain, dns and cloud server on which my website is hosted.
DNS panel looks like this :
(As seen in other posts, I tried do delete AAAA entries but I can't do that without deleting every entry with the service starting like "Redirection:", fataly return a 404 error)
The version of my client is (e.g. output of certbot --version or certbot-auto --version if you're using Certbot): certbot 1.8.0
Those redirections are the issue here. Those are redirections from a year before I was born: <frameset> redirections.. There's no valid reason for those redirects any more IMHO. Also, the Let's Encrypt validation servers won't work with these kind of """redirects""".
Is there a particular reason you've got these <frameset> """redirects""" in place?
Personally, I would remove all those """redirects""", add your hostname arianeperrinpsychologue.fr to the Apache virtualhost and add a CNAME for @ and www to 33a5c65.online-server.cloud.
I didn't think a CNAME from an apex (@) was even allowed by standards. I've never attempted it though (and certainly won't based on the mail issue @JuergenAuer has mentioned).
However, CNAME records cannot coexist with other records with the same owner name. (The reason why is explored in Appendix B). This restriction means they cannot appear at a zone apex (such as "example.com") because of the SOA, NS, and other records that have to be present there.
