Insecure Connection error message after importing site - can't access site

Hi, I’m having a heck of a time importing my live site into a fresh install on localbyflywheel. I have used the AllInOneMigration plugin and imported all files, but when I click on the link to connect to the site, I’m getting the error message: You Connection is not secure… and I cannot continue. I had clicked on ‘TRUST’ in the ‘SSL’ tab but firefox says it’s a bogus certificate…how can I proceed? I appreciate your assistance!
