i have moodle 3.9 , i installed on it jitsi meet videoconference plugin.
server: debian10 ,
the plugin was installed without errors, on configuration i left all fields to their default values even the domain is left to meet.jit.si.
when i try to use the plugin in a course, it shows in blank page as if there was no thing happened.
what can be the problem and how to fix it?
