Can't get Admin on Mobile

[Birdsafe]

Just started last night - can no longer access my admin on a mobile device. I get "the page you are looking for is no longer active."

You may be going to the wrong link. Try https://www.yourdomain.com/admin and don't let your browser autofill anything more. I suggest clearing the history on your mobile browser to make sure it's not sending you to a link that's invalid.

That is the link I am using. The issue is not with the browser, it's after I click to Login -- it's within 3dcart.
