Thanks for letting us know. We're looking into this issue. I will post a status update when I have one to share. Sorry for the inconvenience and thanks for your patience.
Hm, in the FAQ at https://dev2021.esri.com/faqs the following is stated:
How long can I access the virtual Esri Developer Summit?
Registered attendees will have exclusive access to on-demand conference content until May 8, 2021 after the event has concluded.
Has the date changed? How long can I access the on-demand content? Because of the repeated downtime.
Many thanks in advance!

FYI, I am trying to track down an answer to your question. Still waiting to hear back from the Events team. I will post a reply when I have a status update.
Thanks for your patience,
