 * [@danielt49](https://wordpress.org/support/users/danielt49/) hey thanks for the
   screencast. That’s strange yes, but one thing that pops out at me is that the
   oauth is supposed to be a popup, and not a “new tab” as you showed in the video
   which is odd. I wonder if you have anything in your browser settings that might
   be getting in the way of this to present the popup window ( and really not sure
   if that’s the actual problem either ).
 * Have you by chance tried a different browser like FireFox yet to see if it might
   be browser related?
 * The other thing that comes to mind is that maybe your server has been blacklisted
   by the Mailchimp API gateway. Typically though you would see this in the plugin
   connect page you were just on if it was failing – so I’m not sure if there’s 
   a hidden “alert” we can’t see.
 * Can you please check into your Woo Fatal Logs to see if anything is registering
   there? Or possibly maybe open up your browser console to check to see if there
   are any “console errors” that might be related to this?
 * My gut feeling is that the server might need to be looked at for being blacklisted–
   but it’s really hard to say without checking it ourselves.
