I think I found out what might be happening, doing some tests on my other moodles that are already on the air, I found out that the ones that work with the LTI tool are from versions 4.1.5.
When I uploaded moodle to my server with version 4.2.2+ I didn't pay attention to testing the external tool.
Could there be a bug in version 4.2.2 for the external tool?
I followed this documentation to create my moodle provider and consumer -> if possible, can we update this documentation to the latest version of moodle (this if creating the external tool in 4.2.2 is ok)?
