I am going through the same issue. I used the local host and got the error (7021), then switched to 0.0.0.0/0, and then got the (7015). So, I took your advice, I went into the "NOTIFCATIONS" section of my moodle site, and then saw some errors, and it ultimately said that I need to upgrade my auth_joomdle plugin. The plugin I used was the one I got in the Joomdle 4.0 package install package. All loaded in the backend of my moodle site. I adjusted all the settings according to your instructions, and everything looked great, until I tried to connect. I get the same error:XML-RPC Error (7015): Unable to locate function, or function prohibited for RPC.
Needless to say, can you help me discern the NOTIFICATIONS ERRORS? I have attached a .txt file with them. Any help would be soooooooooo appreciated! Thanks.
