you can put your code?

did you start the Hub Mercure?

HTTP/1.0 401 Unauthorized means that the JWT you provide isn't valid. It's probably not signed with the same key than the one set for the hub.

Can you try to follow these steps? https://github.com/dunglas/mercure#401-unauthorized

A better error message will now be thrown since the Mercure Symfony component now switched to HttpClient.
