Can't connect the Adobe CC app to Microsoft Teams due to a 502 error for ccmsteams.integrations.adob

I own a channel in our company Teams and when trying to connect the Adobe CC app, going through the steps, get to the login screen and it opens an html window to log in to my CC account (which I'm already logged in to so why is it asking me to log in?) but the url (ccmsteams.integrations.adobe.com) throws a 502 error "This page isn't working" (no kidding!) so it halts the process of connecting the CC app into Teams entirely.
