Self-Registration Email Verification 404 Error

Hello - Has anyone encountered a 404 error when a user clicks the “Verify Email” button on the self-registration email verification email?

Does anyone know where this verification link is supposed to send the user?

I have a developer account and so cannot modify anything about that verification email, and I’m unable to determine the cause of the error.

Thank you!

Does this happen every time a user self registers?
Can you register a new account and then copy the link from the email and add it in a post. I would like to verify it is pointed back to your Org and is in the expected format.
