The 'elasticache certificate verify failed' error message occurs when there's a problem with SSL/TLS certificate validation while connecting to an Amazon ElastiCache node. This usually happens because the client application or driver used to connect to the ElastiCache cluster isn't configured correctly to trust the SSL/TLS certificate provided by the ElastiCache endpoint.
Another possible cause of the error is an expired, invalid, or revoked SSL/TLS certificate provided by the ElastiCache endpoint.
To fix the 'elasticache certificate verify failed' error, check if the client application or driver configuration trusts the SSL/TLS certificate provided by the ElastiCache endpoint. Ensure that the root CA certificate associated with the SSL/TLS certificate is present in the trusted store. If absent, download it from the certificate provider and add it to the trusted store.
Besides, updating or replacing the SSL/TLS certificate can help resolve the issue. Create a new SSL/TLS certificate and attach it to the ElastiCache endpoint. Once done, update the client application or driver configuration to trust the new SSL/TLS certificate. If the problem persists, seek further assistance from AWS support.
