Hello,
I have a strange problem with one of my hosts.
I'm getting this error message:
Quote:

Connexion bloquée : problème de sécurité potentiel

Firefox a détecté une menace potentielle de sécurité et a interrompu le chargement de www.bagu.biz, car ce site web nécessite une connexion sécurisée.

Que pouvez-vous faire ?

www.bagu.biz a recours à une stratégie de sécurité HTTP Strict Transport Security (HSTS), une connexion sécurisée est obligatoire pour y accéder. Vous ne pouvez pas ajouter d’exception pour visiter ce site.

Le problème vient probablement du site web, vous ne pouvez donc pas y remédier. Vous pouvez le signaler aux personnes qui administrent le site.


Here is my httpd-ssl.conf : https://pastebin.com/jnT1JMu9
And my vhost config file : https://pastebin.com/hKDYLNfc

I get this message every time I restart the server. And only on Firefox. CTRL + SHIFT + R is enough to display the page properly, but I'd like to understand why this happens, and only on www.bagu.biz.

I also use cloudflare services, in case that has an impact.

Could you please help me?
Thanks

My best guess is your cloudflare config.

I finally found the source of the problem.
I'm using pihole+unbound as a DHCP + DNS server.
I had set the server ip as a fixed resolution on the domain name for pihole, but this was not the case for unbound.
As soon as I removed it, everything started working perfectly again.
So I guess it was a problem for the certificate, presenting sometimes the ip (and therefore not valid for the certificate) and sometimes the domain name (and therefore in this case, valid for the certificate).
