Can't log in to see site

Hi, I’m new to all this and clearly an idiot. I installed coming soon and have a lovely coming soon page on my site. I also white listed myself as a user (admin level) but now I can’t see the pages under construction from my dashboard (the coming soon site is all that I can see) and there’s no “login” on the under construction page. What am I doing wrong?
