Basic call connectivity issues in v.4.3

Hello,

We installed Intel CS for WebRTC framework v.4.3 on Ubuntu 18.04 server. When we are trying to run the sample application, we are getting the below issues:

Note: This is happening with v4.3. only. Our STUN/TURN server is working fine.

Chrome Browser:
publication error Error: "Ice procedure failed."

Firefox:
ICE connection state changed to disconnected 7 owt.js:9:35149

Chào Yanbin Z.

Tôi tìm thấy có sự khác biệt ở logs/webrtc-xxx.log

Ngoài ra các log khác không có vấn đề gì.

Tôi đã thử kết nối với 5 thiết bị PC có gắn camera và microphone với mạng ổn định và 1 luồng Share screen từ 1 trong 5 thiết bị.

Nhưng vấn đề này xảy ra: 

ICE connection state changed to disconnected
ICE connection state changed to closed

Quá trình này lặp lại liên tục, và tôi mong sẽ có sự hỗ trợ tư Intel.

Server test: https://rsv01.suremeet.vn, Version 4.3

Thank you.
Middle Kiên.

Hello Yanbin,

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:

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.
