Error loading the site

[Lindsey]

I'm having issues opening the site on an Android tablet. I managed to open it in a private browser, it said it couldn't make a secure connection and to contact the owner of the site to fix it.
If I try to open it in a regular tab is doesn't load. I couldn't try to log in on the app to see if it has the same issue.

I couldn't take a screenshot of the error in private mode but this was the error code: NET::ERR_CERT_AUTHORITY_INVALID
