New Client but token validation fails in PHP SDK

We created a new Client for a new app. The angular frontend of the app successfully creates tokens and they validate on jwt.io. The PHP SDK in the backend API throws an Invalid Signature exception. Anyone else have this issue.

Gotta loving answering your own question… Here’s what I found that worked for me. https://auth0.com/forum/t/api-check-jwt-signature-verification-failed/4802/2
