Hi guy
I am trying to set up my moodle as LTI provider and another identical installation as LTI consumer.
I followed all the steps and on the moodle provider platform I enabled LTI under Site administration> Plugins> Authentication> Manage authentication and enable LTI and also Site administration> Plugins> Enrolments> Manage enrol plugins and enable 'Publish as LTI tool'.
Created a course on my LTI provider platform, added LTI authentication, generated URL cartridge and secret key to access the entire course.
On the Moodle LTI consumer platform I entered the external Tool resource and configured the URL and the secret key .....
But when I launch the external tool I get the error "An error occurred when launching the external tool:" Sorry, there was an error connecting you to the application. "
I tried to do it both in iframe (I had also enabled the Allow frame embedding item) but it gives the same error.
If I edit the external tool I see that it has recognized the launch links of the type https: //...../enrol/lti/tool.php? Id = 2
It all seems correct, but there is no way to make it work.
Some idea? I've tried them all or almost evidently.
Thank you all
