Code: Distributor ID: Debian Release: 10 Codename: buster Apache2 : 5.6.40-38 ISPConfig 3.1.15p2 Site madeleine.michelis-amiens.lyc.ac-amiens.fr:80 I am very slow on HTTPS sites for more than 24s to display the home page. In HTTP mode madeleine.michelis-amiens.lyc.ac-amiens.fr:80 the site is displayed quickly in 1.1s1 I have a problem with the TLS configuration that does not contain the correct cyphers suites. tested on ssllabs: It is full of "protocol or cipher suite mismatch" errors. So my browser spends 11 seconds looking for a configuration that works with my server. I compared the configuration on the Ispconfig server and the site on https://ssl-config.mozilla.org/ I don't understand why in the configuration of a vhost on Ispconfig we have a hash debant # SSLCipherSuite with SSLHonorCipherOrder at on Same speed insight page cannot test the page: https://developers.google.com/speed/pagespeed/insights/?url=https://madeleine.micheliamiens.lyc.ac-amiens.fr% 2 F Thank you in advance for your answers.
