I have used the Migration form to move a cpanel backup to my new Ubuntu 16.04 VPS with a fresh Virtualmin install on it. The migration successfully completed. In the cpanel backup, there was a main (empty) domain and 7 addon domains with a simple Wordpress site installed on each.
I went ahead and changed the VPS IP for my main domain in Cloudflare’s dashboard, and changed the VPS IP for one of the addon domains, waited a few minutes, refreshed my addon domain main page, and got the error
"This site can’t be reached refused to connect. ERR_CONNECTION_REFUSED"
Did I forget a step in the migration?
[Edit: searching more, I see in Server Status that Apache is not running, and nothing happens when I click on the green arrow to start it. Running sudo service apache2 restart gives
Restarting apache2 (via systemctl): apache2.serviceJob for apache2.service failed because the control process exited with error code. See “systemctl status apache2.service” and “journalctl -xe” for details.
and running systemctl status apache2.service gives
* The apache2 configtest failed. Output of config test was: AH00526: Syntax error on line 226 of /etc/apache2/apache2.conf: SSLProtocol: Illegal protocol 'TLSv1.1,' Action 'configtest' failed.
