I am slowly changing the sites i administer over to https:// sites. To add ssl to the site I got to Edit Virtual Server> Enabled features> and select the checkbox next to SSL website enabled? then save and for each site I get the following output.

The last line has me puzzled can someone please let me know whet the problem and solution are?

What do you get upon using journalctl -f or some other log command?
