Message content not showing in mobile app


All Spok Mobile devices are receiving message alert tones on the phone handset but the app is not showing the message content.


The transmission of message data happens over an SSL connection. Whilst a misconfiguration of the environment can cause this issue to happen, the majority of the time this issue occurs to an implemented site when the SSL certificate for the Spok Mobile message url has expired. The renewal of the certificate requires re-binding to ports 443 and 8091 in IIS. To check if the certificate is expired see options below.
