Issue/Introduction

After upgrading gateway to 11.1.2 , connections from the Adobe Campaign Manager client are failing due to a connection problem with the Message Center. The connection is established via SSL through the Gateway.

The following error currently occurs during the connection test: Error message ‘error: 14094417:SSL’

Environment

API Gateway 11.1.2

Resolution

The problem is that the TLS handshake is failing on the TCP level because the format for the SNI extension is invalid - this should be hostname only.

The newer Java runtime is much more strict to this format than the older version. Disabling the SNI extension does not work at all.

There is no solution for this on the gateway side.  Adobe needs to upgrade their application to conform to the RFC standard.
