Hi @space,
Welcome to the Auth0 Community!
I have just checked the URL you used for the logo URL, and it seems to be directing me to a webpage instead of an image. To set the Logo URL correctly, please make sure to use a direct image URL.
For your convenience, the appropriate Logo URL should be: https://i.ibb.co/3dmd4T9/boltbetzblack.png
I hope this clarification helps!
Please reach out again if you have any questions.
Thanks,
Rueben
