Since my hosting provider (2 days ago) installed ssl let’s encypt i am gatting error with the SSL:
Your connection is not private
Attackers might be trying to steal your information from proiectecaselacheie.ro (for example, passwords, messages, or credit cards). Learn more
But this error is not showing always. Just after a few page refresh’s.
Based on having seen this kind of issue with cPanel before, here is my theory.
The web host has two instances of the httpd process group running:
One group is using the former Apache configuration, which had the self signed certificate
One group is using a newer Apache configuration, that has your Let’s Encrypt certificate
When the newer configuration was loaded, the first httpd process group was not properly reloaded.
This is why if you connect to your site 100 times, you will randomly see the self signed certificate, and randomly see the Let’s Encrypt certificate. You will NOT see both certificates in one connection/TLS session. This can be proven by doing a packet capture across 2 TLS sessions - I have attached one of each.
