I am not able to connect to Moodle as an LTI Provider through an external LTI consumer. I keep receiving the error message Failed request. Reason: Sorry, there was an error connecting you to the application.
I am able to connect to my Moodle course through http://ltiapps.net/test/tc.php.
I followed all the steps from https://docs.moodle.org/38/en/Publish_as_LTI_tool
- Go to Site administration > Plugins > Authentication > Manage authentication and enable LTI
- Go to Site administration > Plugins > Enrolments > Manage enrol plugins and enable 'Publish as LTI tool'
- Allow frame embedding' is enabled (in "Site Administration > Security > HTTP security")
- Course Administration > Published as LTI tools
