Which browser and email app are you using, and does the game's page open normally if you visit it directly on itch.io? Please share the public game page URL, rather than the link from the email.
Thank you for you response.
I am using Google Chrome on Window 11 and GMail.
This is an email that I received today. Again when I press to see the game, I got a Bad gateway msg.
Yes, on the direct page everything works fine.
