Alexa enable skill not directing to HA login page

Hi all! I’m having the strangest issue with the Alexa integration. I’ve followed all the steps as per the guide and everything works perfectly up until the Account Linking section.

I’ve looked all around the forums and Reddit, but my issue seems a bit different. I open the Alexa app, find my skill, click “Enable to Use” and then instead of seeing the Home Assistant login page pop up it says “Alexa is looking for devices to connect…” and after a few seconds “Alexa couldn’t find a new device to connect”.

I went over my steps multiple times and double checked everything with the guide, but can’t see what I’m doing wrong. Any thoughts on what the issue could be?
