If you are able to login to the console, but your status never switches to "Online" and displays "Offline", it most likely means that the plugin cannot connect to the SightCall's Platform.
This could be due to different reasons, below are some common reasons and ways to verify if they apply to your situation:
Restrictions on your network
The security policy of your network, either corporate or personal, could be too strict.
In order to test this, you can try by connecting to a different network like your home Wi-Fi, or tethering with a personal smartphone.
If your status changes to "Online" on these other networks, this indicates that the security policy of the network you were using is too strict. In this case you should ask your Network/IT department to apply the network requirements outlined on this page.
Computer System's security policy
Your computer's own security policy could be too strict
If despite following the steps outlined in the previous section, your status remains "Offline", it is possible that your computer's own security policies are too strict, this is common on company-provided computers.
If you are able to, you can attempt to connect to the SightCall console from a different computer, preferably a personal computer.
If your status changes to "Online" on this other computer, this indicates that the security policy of the company-issued computer you were using is too strict. In this case you should ask your IT department to apply the requirements outlined on this page.
