Hi there. - Linux Distribution and version used on your server. - debian 8 - ISPconfig version - 3.1.2 I've noticed the following problem: First of all, this happens ONLY when I upgrade ispconfig from 18.104.22.168pX to 3.1.x - clean installations 3.1 don't have such problem. What I've also noticed is that inside of ispconfig.conf there were few lines missing: I've added that and I'm still not able to generate letsencrypt SSL from Ispconfig. Manually, command line I can - so it's definitely some kind of ispconfig related problem. What to do/how to fix it?
