When switching to RS256 nothing works.

I switched to RS256 as stated in the description

JWT_AUTH_ALGORITHM

The jwt_auth_algorithm allows you to modify the signing algorithm.

I get errors:

Were you able to come up with a solution?

[UUSR]

Unfortunately no.

Hey @UUSR, I solved this today. If you still want to use this plugin/method, here: https://github.com/Tmeister/wp-api-jwt-auth/issues/280

Closing this.
