To check network connectivity on the mobile device, check your device’s Wi-Fi or network carrier settings to ensure that you have connectivity. Use your internet browser to ensure that you can connect to an intranet website. If you had connectivity but the connection was lost, this was possibly environmental. Ensure you are in a place where the connection is reliable. Turning the device’s Wi-Fi connectivity on or off during an operation will likely cause a connectivity issue.
To check that the server’s network connectivity is working, try to connect from a different mobile device. If this fails and all clients are failing to connect, follow your process for checking system connectivity and integrity. For example, check that the MyID system is running, that the IIS server is running, the firewall is operating correctly, and any load balancers are correctly configured.
