Remote Admin Error

I had to go on the road this week and decided to try out remote Admin, but I've yet to get it to work.

When trying to access the https://remoteaccess.aws.hubitat.com/ url provided by the Hubitat app it doesn't appear to load then eventually gives me an Invalid Hub ID error.

Can anyone suggest next steps? The hub is obviously still online, but I'm not home to access it directly nor is my VPN working (fun to find out now...) so I can't do local admin.
