Environmental requirements

If the user is in a restricted network (such as a corporate intranet with a firewall), it may be restricted by the firewall and cannot attend classes normally. At this point, you need to configure a whitelist for the following domain names and ports in the firewall:
TCP port:8687
UDP port:8000,8800,843,443
domain name:qcloud.rtc.qq.com

Camera and microphone permission problem

Due to system permission settings, browser permission settings, or device occupancy, there are scenarios where the camera and microphone fail to be turned on. The specific tips are as follows:
