Hello all!

I am trying to get the Web Push API to work with my app and Safari on iOS. I can register fine in Safari ... But, when trying to send my request to the endpoint I receive a 403 with reason: BadJwtToken.

I've verified the token being sent in the Authentication header is valid. Also, the code I am using to send the Push request works perfectly on Chrome & Edge.

Has anyone else experienced this behaviour? Any suggestions would be greatly appreciated.

Really can't believe this was so simple in the end. The problem was the subject in the JWT. I actually did have subject, but it was malformed (or at least malformed according to Apple's restrictions). My subject was in the format "mailto: <email_address>". It seems Safari doesn't like the space or the angle brackets.
