Invalid Push Certificate

Invalid Push Certificate is thrown when Apple returns a BadCertificate error. This means your certificate was rejected by Apple and may be expired, revoked, or invalid.

Steps to Resolve

Generate either a new p12 certificate or use the p8 authentication.

• iOS: p12 Generate Certificates - needs to be generated every year
• iOS: p8 Token-Based Connection to APNs - only needs to be setup one time
