Ocsp.int-x3.letsencrypt.org error

Bonjour.
Je viens de remarquer que j’ai une erreur qui revient souvent :
ocsp.int-x3.letsencrypt.org could not be resolved (5: Operation refused) while requesting certificate status, responder: ocsp.int-x3.letsencrypt.org
Mon certificat est pourtant valide.
J’utilise NGINX.
Pourriez vous m’aider à résoudre ce problème ? J’ai cherché sur le net mais rien n’a apporté de solutions.
Merci d’avance.
Tom

What value are you using for resolver in nginx?

https://nginx.org/en/docs/http/ngx_http_core_module.html#resolver

Maybe try:

resolver 1.1.1.1 8.8.8.8 1.0.0.1 8.8.4.4;

This what i have :
resolver dns112.ovh.net ns112.ovh.net 1.1.1.1 8.8.8.8 1.0.0.1 8.8.4.4 valid=300s;

Remove these.

They must be recursive resolvers, but these are actually only authoritative nameservers - so they respond with REFUSED to all non-authoritative queries.

Once they are gone, nginx will be able to resolve the OCSP domain.
