My domain is: helpdesk.espro.org.br
I ran this command: as many commands as I found in forums (openssl s_client, curl, nslookup)
It produced this output: None of then produced something useful to solve the problem
My web server is (include version): Apache 2.4.25
The operating system my web server runs on is (include version): Debian 9
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): no
The version of my client is (e.g. output of
certbot --version or
certbot-auto --version if you’re using Certbot): certbot 0.37.1
Here is my problem: I’ve been using certbot for the last six months without any problem. Never seen any kind of slowdown on incoming connections due to ssl problems, but last Thursday (Jan 09) my certificates got renewed, and since then my web sites became very slow. First thing I saw was that in Chrome console on network tab the ssl phase is taking at least 29 seconds to complete after the request starts. It feels very strange because I’ve never had any similar problem before, and now I can’t seen to debug, because every tool I found looking into related forums didn’t gave me any clue, except for the slow response.
I’m not much experienced in debugging network related problems, because i never had to, so any help is welcome. Plus, I don’t know how to check if there is any problem with https certificates validation on web browsers.
