No route to token endpoint

Hi!

Hope you can help me solve my problem.

I have installed and activated the plugin. I then went to the settings and selected, JWT authentication, entered a secret and clicked on Save Configuration, but the endpoint for retrieving a token (wp-json/api/v1/token) doesn’t seem to be registered. I receive a “rest_no_route” error message when trying to access it by a browser and using curl it gives me a 401 (Unauthorized).

I assume it’s some server configuration that requires to be changed?

Cheers,
Oliver
