Dear Juan Carlos,
Thank you for your responsiveness and your recommendations, indeed it seems to work better with double quotes "URLPATH = / moodle". I have a warning telling me that my certificate is not valid, the one generated during installation. The user must accept an invalid certificate.
Do I need to generate another certificate via (Lets Encrypt) or a certification authority?
Testing as a student, when the student asks the program to assess it we get messages "@error".
Is this normal?
I will conclude by saying that I have great admiration for the work accomplished.
