What Do I Need to Do Before Going Live?

This is a checklist we have put together to make sure you have the best experience possible for your first webinars. We split this post into three section:


Before you start

Before you start broadcasting make sure you have checked the basics:

  • Use Chrome (always the latest version if possible)
  • Clean your cookies
  • Make sure you do not have the same (or another) webinar room opened somewhere else
  • Make sure there's no multiple login through your host account

Check your hardware

Make sure your microphone and webcam are working properly:

  • Does Chrome detect the mic/webcam?
  • Is the hardware access authorized?

To make sure your hardware is properly plugged in and working, you can use our hardware check module:

Double check if people can hear you:

Now you can check if everything is working by asking your contributors to join the room ( don't start the webinar, they can join even if it has not started). If they can hear/see you then you're good to go. You can also try by using a meeting software like appear.in that works in the browser, just like us.

Check your bandwidth

We can only make the best effort as we rely on your connection and your attendees' connection to have a good webinar experience. You can make an  automated test here and send us the results. 

Here's what you can do to maximize your chances:

Make sure no firewall will stop you from broadcasting

Ask your system administrator the following:

  • Is the port 443 open to download a video stream?
  • Can we send and receive websockets?
  • Is it possible to open UDP port 3478?
  • For the best possible experience, is it possible to open UDP ports 1025 to 65535?

Make sure your bandwidth is healthy

  • Can you download and upload 10mb/s?
  • Is the connection stable (do you experience ups and downs in terms of quality? Is the connection breaking?)
  • It's better to use an Ethernet connection instead of Wifi if there are too many people sharing the same network

Check your setup

There are a few things you can do to make sure you will host a good, professional webinar:

  • Use earphones (iphone earpods are great) to avoid the echo in the room
  • If anyone is listening to the webinar in the same room, make sure they're using earphones as well otherwise the sound will loop back in your microphone and create a Larsen effect.
  • Kill ALL the useless apps that might eat your CPU (computer power) and bandwidth. Google Drive sync typically.
  • Sharing a screen? Or a presentation? Read this.
  • Having the 2nd monitor is the best setup because you can have the webinar in one window and something else on the other one: a presentation, a chat with your team, etc.

Not working? 

Having an issue with the connection? Try the following procedure:

  • Use a different browser: 
    • As a host, make sure you are using the latest version of Chrome
    • As an attendee, make sure they're using one of those browsers.
  • Try using incognito mode
    • If it worked, you have a cookie problem or a conflict with an extension. Clean the cookies, remove blocking extensions, logout from Livestorm and log back in.
  • Try switching networks
    • If it worked you probably have a network issue with a specific network, please refer to the bandwidth section of this page.
  • Try using a 4G/LTE network
    • If it worked you probably have a global network issue please refer to the bandwidth section of this page.
