So all of a sudden today, as of about 11am mst, absolutely none of my users can log into our custom external app via OAuth..

Every single one of us is getting a 401 exception with some cloudlfare message popping up telling them to contact the admin....

Well I have no idea what the hell is going on so... what's up? This is affecting business and costing us money...

Sorry to hear you are having issues there. I have created a ticket for you on this, so we can get it looked into for you. Someone will be in contact as soon as possible.

For reference: 

Here's what I get when I try to log in externally: 

and what my partner is getting on his end now: message-3.txt

 

Thank you. Ive added all the info we need to the ticket for it to be looked into
