Hello, I have a weird case here. there are 4 people lets name it A, B, C, D.
A B C connect to public wifi network
D connect to enterprise network
And here is the case:
- A B C , 3 of them doing conference on room1
- When D join the conference on room1, he can’t connect. The Image is just black and no sound (from A perspective). But A B C still connected and can talk to each other.
- But A can connect p2p to D, also B can connect to D and C can connect to D.
- When A and D connect p2p, B try to join. D suddenly turn to black image(from A perspective), but A and B connected and can talk each other.
First i thought its because of the D’s network firewall, but if that’s the case, we wont be able to connect p2p also right?
The problem here is maybe the UDP package of D is not sent to the STUN server. But what can cause this? And how we fix the problem? any idea? This is few info form D perspective when we try the case number 4:
