I can confirm this problem. This is leaving the service in a pending status even though the SSL cert is created.
Here is a snippet of the error:
INPUT:
my@email.com|ssl-activate
i:91094;
This will say success.
OUTPUT:
my@email.com
a:3:{s:5:"error";b:1;s:7:"message";s:34:"The requested method was not found";s:11:"description";s:19:"Unknown API method.";}
I have the correct email address for obvious reasons.
