Detail: No valid IP addresses found for bbb.univ-fcomte.fr

Hi,

I have setup a A name 'n PTR for my domain.

When I check on an OVH server I get :

nslookup bbb.univ-fcomte.fr
Server: 127.0.0.1
Address: 127.0.0.1#53

Non-authoritative answer:
bbb.univ-fcomte.fr canonical name = pres-115.univ-fcomte.fr.
Name: pres-115.univ-fcomte.fr
Address: 194.57.76.115

Ant ptr :

nslookup

set type=PTR
194.57.76.115
Server: 213.186.33.99
Address: 213.186.33.99#53

Non-authoritative answer:
115.76.57.194.in-addr.arpa name = bbb.univ-fcomte.fr.

But I get always error :

certbot --webroot -w /var/www/bigbluebutton-default/ -d bbb.univ-fcomte.fr certonly
Saving debug log to /var/log/letsencrypt/letsencrypt.log
Plugins selected: Authenticator webroot, Installer None

IMPORTANT NOTES:

Someone have an idea ?

Thanks

Hi @GeraldGeniaut

there is a check of your domain - one hour old - https://check-your-website.server-daten.de/?q=bbb.univ-fcomte.fr

There is no problem visible. But checking your three name servers manual:

One has a timeout
One has the NXDOMAIN
One has the ip address.

Checked with Unboundtest - https://unboundtest.com/m/A/bbb.univ-fcomte.fr/UAU77AFC - the same:

Response:
;; opcode: QUERY, status: NXDOMAIN, id: 25305

May be you have to wait, because your name servers are buggy.

PS: Checking the main domain - https://check-your-website.server-daten.de/?q=univ-fcomte.fr

X Fatal error: Nameservers mit different SOA Serial Numbers

The zones have different informations.

Hi,
