Troubleshooting: Issues Connecting to a Goldcast Event

Learn how to troubleshoot common issues connecting to a Goldcast event and ensure a seamless virtual experience.

Follow these steps if you're having trouble connecting to a Goldcast event.

If your internet connection is poor, you may experience issues:

  • Unable to join sessions
  • Getting disconnected from sessions
  • No audio or video
  • Audio lags
  • Blurry, choppy, or pixelated video
  • Difficulties accessing platform features like the microphone, camera, chat, polls, or Q&A

If you encounter any of these issues, try switching to a different network or ensure you have a stable internet connection. You can verify connection speed using a tool like Speedtest by Ookla - The Global Broadband Speed Test.

If your connection speed is good but you're still experiencing connectivity issues, check whether you're connected to a VPN. If possible, disconnect from your VPN—some VPN configurations block WebRTC traffic. For more guidance, read here: Configuring Your Network, VPN, and Firewall Settings

If successful, they should see something like this:

If unsuccessful, they should see an error message like this:

This doc now assumes that your VPN was not able to connect to the public tech check page and explains how to solve the issue.

Domains

*.agora.io 

*.sd-rtn.com

For WebRTC streaming. A block on this could prevent real-time audio and video streaming.
  • Option 2 - If domain whitelisting is not an option for Agora, do the following: Whitelist specific IPs and ports. Port will be 443, and protocol can be either UDP or TCP.
