I have deployed a simple questionnaire as an HTTP and LTI-based external tool using Tsugi (more specifically this example https://github.com/tsugiproject/tsugi-php-module).
I am trying to add this questionnaire as an external tool to Moodle 3.4.3 but a blank page appears. I have looked at some forums and they say that the problem might be that the service is HTTP-based and Moodle is HTTPS based. So I tried the following things:
- I changed my service to HTTPS-based: I tried to put my Tsugi service in a HTTPS-based server but a blank page appears instead of my questionnaire.
- I changed my Moodle configuration while my service is HTTP-based: I tried to connect my HTTP-service and change my Moodle configuration: I went to Site administration --> Security --> https and I deactivated "only secured cookies" and I activated "allow frame embedding". Another time a blank page appears instead of the questionnaire.
I wonder what can I do to solve this problem.
