ICE failed, add a STUN server message in v.4.3

Hello,

We installed Intel CS for WebRTC v.4.3 on Ubuntu 18.04 operating system. When we are trying to run the default (sample) application, the calls are disconnecting and getting "ICE failed, add a STUN server" (OR) "subscribe failed Error: "Ice procedure failed." messages. We are getting this message, even though we added STUN server in webrtc_agent/agent.toml file.

Anybody able to run the sample application by deploying Intel CS for WebRTC framework globally?

Please find the complete log:

subscribe failed Error: "Ice procedure failed."

Hi, 

Hi, 

If you add a STUN server, you need change the default JS sample (usually: extras/basic_example/public/index.js) by adding configuration when creating conference client to make it work.

Hello Li,

Hello Li,

Thank you for your reply. We haven't found "index.js" file in extras/basic_example/public/ folder. But, found "index.js" file in extras/basic_example/public/scripts/ folder. But, I haven't found any parameter or part to add STUN details in extras/basic_example/public/scripts/index.js file. Could you please tell where we have to add STUN details exactly?

Thank you.

Best Regards,
Chandramouli.

Hello Li,

Hello Li,

If I am correct, we added STUN/TURN information in extras/basic_example/public/scripts/index.js file as below:

   ---------------
   ---------------   
    conference = new Owt.Conference.ConferenceClient({ iceServers:  [{
    urls: "stun:abc.def.com:80"
  }, {
    urls: "turn:abc.def.com:443",
    credential: "password",
    username: "username"
  }]
}
);
  ---------------
  ---------------

Although, we are getting the same issue. More over, we found the below error in most of the log files after executing the "sudo bin/start-all.sh" command:

2020-01-08 16:03:33.720  - INFO: WorkingNode - pid: 12230

Please note that we are getting all these issues in v.4.3 only. Hence, request you to help us to resolve the issue.

Thank you.

Hello Li,

Hello Li,

Good evening and thank you for your reply. We are following same installation process only to 4.3 version, like 4.2 and 4.2.1 versions. The same environment is successfully working in 4.2.1 version. Also, same environment with STUN/TURN server, 4.2.x works fine while 4.3 is not working. As I noticed, there are no error messages in logs. Anyway, please find the below information as you asked:

Environment:

Server (MCU) Operating System: Ubuntu 18.04 Server (Minimal version - command line only) and CentOS 7.x (Minimal version - command line only)
Linux Kernel Version: 4.15.0-69-generic (Default) and 5.3.6 (Low latency - Updated)
Browser: Google Chrome Version 77.0.3865.90 (Official Build) (64-bit) and Firefox on Windows 10 Pro
Intel CS for WebRTC Version: 4.3
Firewall: No firewall and all ports are opened
Cloud Environment: AWS

Installation Steps:
1) Installed updates and essential common development libraries
2) Removed firewalld and iptables
3) Installed RabbitMQ, and MongoDB in the same server only
4) Installed NodeJS 8.x
5) Download and unzip CS_WebRTC_Conference_Server_MCU.v4.3.Ubuntu.tgz
6) Installed dependencies in video_agent folder (./install_deps.sh)
7) Installed openh264 library in video_agent folder (./install_openh264.sh)
8) ./compile_ffmpeg_with_libfdkaac.sh in audio_agent folder
9) cp ffmpeg_libfdkaac_lib/* lib/
10) Installed dependencies (./install_deps.sh) in conference_agent, streaming_agent, recording_agent, and sip_agent folders individually to avoid "Connection to rabbitMQ server error Error: libavformat.so.58: cannot open shared object file" error.
11) Changed private IP address and public IP address in the respective .toml files (as same as v.4.2.1)
12) sudo bin/init-all.sh [--deps]
13) sudo bin/start-all.sh
14) Run the sample application from the browser

Please find the logs that you asked in the below link:

https://pastebin.com/be7MSVKU

These are the steps that I followed. Please correct me, If there is anything wrong. If you need any other information, please let me know. I look forward to hearing from you.

Thank you

Best Regards,
Chandramouli.

Hi,

Hi,

I see your log  contains "libavformat.so.58: cannot open shared object file: No such file or directory".

That means ffmpeg libs are not installed. You can run "bin/init-all.sh --deps" to install all dependencies.

Hello Li,

Hello Li,

Good evening and thank you for your reply. We solved the "libavformat.so.58" issue by installing the dependencies. Although, there is no relation between this issue and "ICE failed" error. Hence, we can close this thread and redirecting to the below similar thread"

https://software.intel.com/en-us/forums/intel-collaboration-suite-for-webrtc/topic/842374#comment-19...

We look forward to your help.

Thank you.
