Environment
Novell Data Synchronizer Mobility Pack
Situation
Some devices unable to connect to the Mobility server.
Unable to connect to Mobility server using the DNS address or ip address of the server when connected to WiFi.
Unable to connect to Mobility server using the DNS address or ip address of the server when connected to WiFi.
Unable to connect to Mobility server with both WiFi and 3G or 4G enabled.
Other devices are able to connect using the DNS address from outside the network.
Resolution
Verify the information is added correctly on the device:
- If the server is using a self-signed certificate, please verify that Accept all SSL certificates is checked.
- Otherwise, provide the correct information for the account and the server.
- Disable WiFi on the device and rely strictly on 3G or 4G, or try using only WiFi instead of 3G or 4G.
- Try adding the account again to the device. If connection works properly, the network needs to be properly configured to route requests (external and/or internal) to the server.
Verify the server's certificate:
- From any web-browser visit: http://www.digicert.com/help
- Provide the server address that is entered on the device.
- If the Common Name is not equal to the server address entered on the device, this can sometimes cause problems. Please follow TID 7007674 to properly configure a new certificate.
Cause
With both WiFi and 3G or 4G enabled, the device relies on WiFi for
DNS resolution. DNS address and public ip address of the server are
improperly routed internally and cannot be resolved, therefore the
device is unable to connect.
