Site going insecure
I am collaborating with a fellow repler (tussiez), and he and I are experiencing a problem where the site goes insecure. If you click the little "i" icon to the left of the address (chrome), it says the site is not secure and doesn't show a certificate. However, in dev tools it says certificate is valid and trusted, but doesn't allow you to view the certificate. It also says "This origin is a non-HTTPS secure origin." This is the same message I get in localhost, so I don't get what is happening (since I am going to the https URL of the site).
I think this may have to do with service workers, as my other site I made myself has this problem too, and it runs a service worker (as well as the site I am collaborating on with tussiez). Could this be a repl.it problem, or is it just something with service workers? I really would appreciate the help.
