Technical requirements for webinars

Technical equipment

To connect to the webinar a current office computer 💻 with an internet connection is sufficient.

The recommended connection speed is 5 Mb for downloading and uploading data. You can check the speed of your internet connection here: If you can, use a cable internet connection instead. A wi-fi connection with a weak signal or in a location with multiple people connected may cause the webinar to drop out.

We recommend using headphones 🎧 for uninterrupted listening and higher volume. You can also use your computer’s speakers, but sometimes the performance of the speakers on a laptop is poor.

Web browser

You can use Chrome , Firefox , Microsoft Edge or Safari web browsers to participate in the LiveWebinar online training.

Test your computer

To test your computer before the webinar, you can use the test you can find here. 🧰 The test will check your internet connection, the suitability of your browser and the functionality of your audio devices.

Mobile devices

For mobile device 📱 users a web browser connection is available on your phone or tablet. For example Chrome and Safari browsers are available. 

Technical problems during the webinar

If you experience a sound failure or presentation stutter during the webinar, it is highly likely that your internet connection is not of good quality. In the event of an outage, press the browser page refresh key ⌨️ (F5 or Cmd+R for Mac). The connection will be restored and the problem should disappear. In case of repeated problems, contact webinar technical support via chat or phone. 🙋

Firewall settings (for IT staff)

For the proper functioning of the webinar in the LiveWebinar system please set your firewall as follows:

  1. Enable WWW traffic using Secure HTTP (HTTPS) – for the webinar landing page or registration page.

  2. Enable TCP protocol (secured via TLS) on port 443. This is used to connect to the communication server, transfer chat, etc.

  3. Enable UDP protocol (secured via TLS) on ports 443, 3478, 5349. Used to transfer multimedia streams (audio and video stream of tutor).

  4. Add the following address to the DNS whitelist: *
