Hello!
I installed a Matrix and an Element server and connected them to Moodle using the new Core plugin. I then set up communication in a course and can also connect to Element myself. The Moodle course has a chat room in Element and I also see my participants from the course in Element. However, when a participant tries to log in, I always get the error message that the login name or password is incorrect.
About tips I would be glad!
Best regards
Friedhelm
