3:18:46 PM The system has completed the AutoSSL check for “cprn”.
3:19:02 PM The queue contains a request for a certificate for “cprn”’s website “lue.heliohost.org”. The system last polled for this certificate at May 17, 2018, 7:18:46 PM UTC. The next poll will be no earlier than May 17, 2018, 7:23:46 PM UTC.
Something is keeping it from finding the validation file. The most common cause is an .htaccess with a forced SSL redirect or other rewrite command that prevents plain HTTP access to the .well-known folder.
