I'm trying to install ISPconfig 3 on my VPS running CentOS 7 x64. Followed exact steps from this article: https://www.howtoforge.com/perfect-server-centos-7-x86_64-nginx-dovecot-ispconfig-3 Everything goes without problems until I get to a point just after installing the ISPconfig, when I'm supposed to finalize the installation for roundcube by goint go myservername:8081/roundcubemail/installer - I get an error: ERR_CONNECTION_TIMED_OUT. Same thing happens when trying to access the panel on port 8080. Moreover after running the panel installation I can no longer connect via ssh as root. I can still connect through a generated ssh session credentials (from VPS admin panel).
