Error 403 all of a sudden

Hi, I’ve been using your plugin for a few years, and had no problems until yesterday. When I make a call I get this error:

{“success”:false,”statusCode”:403,”code”:”jwt_auth_no_auth_header”,”message”:”Authorization header not found.”,”data”:[]}

I did nothing, but there was an automatic WP core update, from 6.1.1 to 6.2

Your plugin is also updated.

Thanks for any help or suggestion
