Hi @juan9302,
Your project looks fine from our end. Looking at that error in your screenshot it appears that google accounts reset your connection. Also, the google account says En pausa in the top right, which means you need to log back into your google account. I think when you've logged back in to your google account, you should be able to log back into rstudio.cloud
Please let me know if that is not the case!
