Hi there, first of all, great piece of software, keep up the awesome work! I noticed that the default-included dhparams should now be considered as week with a 1024bit lenght. Maybe you should include a 2048 key or generate a new one on the install?? I used the auto-installer under https://www.howtoforge.com/tutorial/ispconfig-install-script-debian/ so probablly its related to it. Kind regards
