Hi to all, i have this strange problem. I have a fresh "The Perfect Server - Debian 9 (Nginx, BIND, Dovecot, ISPConfig 3.1)" installation with 20 sites. 19 Sites works great with their letsencrypt ssl certificates, one no. If i flag both "SSL" and "Let's Encrypt SSL" option, after update they not remain flagged. If i run "/usr/local/ispconfig/server/server.sh" manually, this is the output: In letsencrypt.log Where is the problem? Thanks!
