Issue with forward Stream

[Naresh_R_1]

Dear Team,

We installed Intel CS MCU 4.1 in AWS cloud and opened all ports, below is the configuration for webrtc_agent. used nginx as reverse proxy webserver and with https SSL Certificates 

network_interfaces = [{name = "eth0", replaced_ip_address = "18.136.148.95"}]

maxport = 49152 #default: 0

minport = 65535 #default: 0

When we try to open basic example app with forward true we are getting below error when it is opened in 3 tabs and we have restart mcu again

but with mixing its working fine with multiple tabs

Kindly help with the issue

Naresh, from your configuration, maxport is smaller than minport, please configure them with valid value

maxport = 49152 #default: 0

minport = 65535 #default: 0

I have the same issue when i try to run webrtc-agent inside of a docker container, this is the log file

Hi, Le, Samuel

If you start webrtc-agent in a docker container, was your network ok?

Have you tried with docker network=host?

[Le__Samuel]

Obviously, I have been using network = host and 2 virtual machines:

1, first one runs cluster_managers, nuve, rabbitmq, mongodb

2, second one runs portal, conference agent, webrtc agent, audio, video, streaming agent, all inside of a docker container.

Do i need a Turn server in this case ?

[Le__Samuel]

Hi there, I found the solution:

this error is caused by the difference between the default network interface name of different Ubuntu machines.

make sure you run the command "ifconfig" to see your existing network interfaces before specifying : network_interfaces in webrtc-agent/agent.toml
