Problem with access to lesson

[Tempolier]

I am experiencing an issue when trying to access the lessons. Whenever I attempt to watch any lesson, I see a Vimeo tag and a prompt to sign in, which I did not encounter before. Previously, I was able to watch the lessons without any problems. However, after signing in to Vimeo, I found that I do not have the necessary permissions. When I return to Coders School, I receive a message stating, "Private video. Sorry, you don't have permission to watch." I would like to mark everything that was working correctly earlier. I am attaching a screenshot for your reference.
