If you receive the 'Hmmm... can't reach this page' error instead of the Beam landing page when you are registering your company with Beam, there is a simple workaround.
Check the Beam URL in your web browser for the text '-live'.
If present, remove only the '-live' text from the URL so that it starts with //participant.beamconnect.com.au. Retain all other text in the URL.
Load the URL again to display the landing page.
