Does anybody know what this Error says or where it is coming from ?



The issue I am having:
when I change my website from http towards httpS, the website is loading extremely slow, sometimes I am waiting for 1 minute in order for the "Forum" to load.
Does anybody have an idea, what could be the issue of extremely slow loading (1 minute wait until page loads) when switching from http towards SSL ?


I am having the following setup:
XenForo 1.5.16
SSL-certificate via LetsEncrypt.
PHP 7.0 (Apache-Modul), MySQL 5.7 and Apache 2.4 (http/2 Support).



Many thanks for help !
