Jitsi "something went wrong" error after 10 seconds

Please help, we are installing Jitsi on Ubuntu 18.04 (Amazon Instance) and only allows two participants for 10/15 seconds and kicks out one of them. We have read everything about this problem in the blog but cannot find a solution. Here are the logs:
