Demo Openemr Patient Portal

Hello Team, I was investigating the Demo Openemr Patient Portal. While I am trying to login the portal using the patient login credentials provided by you, I am getting this error

Oops!
Something went wrong. Please try again.

Also, I am not receiving the registration link on my mail id when I am trying to register myself on the demo portal…
I request you to help me with the same,
Regards,
