Webscoket error connection problem in bigblueutton

Question

I just deploy bigbluebutton using amazon lightsail. Everything is working fine except audio call and video. When I'm trying to connect audio call and video call I'm getting webscket error. I've already disable all the firewall.

I deploy bigbluebutton using bbb-install.sh https://github.com/bigbluebutton/bbb-install

Here is system specifications

ip-xx.xx.xx.xx

After searching here and there i found this one, But i'm also not sure weather this one works properly or not. https://github.com/bigbluebutton/bigbluebutton/issues/2628#issuecomment-635107717

What is difference between single colon and double colon in this file WebRtcEndpoint.conf.ini

I'm also little bit confused about some of the terminology used here like internal ip and external ip. and stunServerAddress=64.233.177.127 stunServerPort=19302 Just copy from github. What kind of ip shoud i use here, internal ip or external ip. `

Answer 1

Check /opt/freeswitch/etc/freeswitch/sip_profiles/external.xml settings firstly. if your binding is like that:

ws-binding: :5066
wss-binding: :7443

change it to like this:

ws-binding: your_external_ip_address:5066
wss-binding: your_external_ip_address:7443

Your external ip address is same with external_sip_ip address.

Then dont forget to restart bbb (bbb-conf --restart)

Answer 2

I think that this problem has arisen from a firewall issue, Check your firewall and be sure that UDP traffic can pass over the firewall.
