Cannot enter DELL rewards sweepstakes

Hello! Thank you for reaching out to us. I am your Dell-Cares contact for order related queries. Unfortunately, our customer service is currently unavailable. We are available Monday through Friday. Please reach out to us on any of these days and we will be glad to assist you. Thanks for being a loyal Dell Technologies customer.

Until you get a response from Dell, take a look on this forum and follow the progress in other threads as some other users also have reported the sweepstake link issue.

Gathering the posts I've seen so far, very likely that those prizes were given ($25 USD) to all users at every plays and Dell has given out all the planned prizes within just two days.  Am guessing the sweepstakes is temporarily closed for now until Dell rewards team can figure out how to keep the promotion going with planned dates.
