Hello, I've been running ISPconfig successfully for a couple of days with Debian 8 to play around and test some stuff. Today I updated to 3.1.1p1 and see a rather weird behavior with Letsencrypt. Once I enable Letsencrypt on one website it works as it's intended to. As soon as I enable it on a second website, the first website throws an error 500, and the second website works well. So I disable Letsencrypt and SSL on website one and enable it again, just to see that website one is now working with SSL, and website two throws an error 500. I am confused to say the least. I don't get any info in the apache error and access logs for the website that is not working. I also cannot find anything suspicious in the fail2ban or letsencrypt logs. Could anybody help me out here and point me into the right direction? Many thanks!
