Unable to connect to moodle

I'm running:
Joomla! 3.4.8 Stable
PHP 5.4.37
Moodle 2.9

when I try to configure the two systems to communicate with each other (they are on seperate servers) I get the following error messages:

Joomla:
Joomdle Web Services An unexpected error happened: 404: Unknown error

Moodle:
Coding error detected, it must be fixed by a programmer: Cannot find file with external function implementation (this happens when I am trying to add the functions on the external services)

Please help, I need this to work,

Enable debugging in Moodle to get more info about 404 error.

As for the moodle error: I don't know why you get it. Try re-creating the service from scratch.

Hi,

I've recreated several times, getting the same error. This is what the debug returns:
Debug info:
Error code: codingerror
Stack trace:
• line 51 of /lib/externallib.php: coding_exception thrown
• line 199 of /admin/webservice/forms.php: call to external_function_info()
• line 191 of /lib/formslib.php: call to external_service_functions_form->definition()
• line 60 of /admin/webservice/service_functions.php: call to moodleform->moodleform()

There is nothing there about Joomdle, so I don't know what is causing it.
I don't remember anyone reporting this problem before, so it may be related to your installation. Maybe you can upgrade Moodle to be sure everthing is fine... From waht you say, it is complaining about missing gunctions before you even add them.

I did a quick search on google and most of the above messages point to an external database and/or log in forms. Have you configured other SSO or other enrollment options. I would search for those errors in moodle / google and see where that takes you.
