redirect issue

This page isn’t working redirected you too many times.

That's what I get when trying to log in to
All I'm trying to do is log in. Win 10. Tried incognito. Tried deleting all garmin cookies. Tried Edge browser with the same result.
When I search the issue I see the same issue unresolved from 7 and 10 years ago.
I just need to add some .gpx files to my inReach unit for work. When I plug in the inReach I get a beep like I plugged in a USB device but nothing shows up on my machine.
