Secure Mail Issues with Android Push Notifications
Article ID: CTX461561
Updated On:
Description
SecureMail on android devices was not getting background push notifications, therefore users had to manually open SecureMail to check for email.
When examining network traces from the ADC, we observe connections to certain Google owned IP addresses are being blocked.
Resolution
The issue was resolved by opening additional targets in their firewall as follows:
- *.googleapis.com
- *.apis.google.com
Problem Cause
EWS notifications to SecureMail were blocked due to firewall restrictions.
