"Error 0"
Posted by Respondus Support
The "Error 0" message indicates a problematic connection to our server at: smc-service-cloud.respondus2.com.

LockDown Browser is attempting to get information about the exam, but is unable to because the Chromebook is not permitting you to connect to that server.

It is most likely caused by a firewall blocking the request LockDown Browser is attempting to make.

* You should restart the router, then the Chromebook and try again.
* Trying a different Wi-Fi network may be necessary if the problem persists.

If the problem is occurring with a managed Chromebook owned by a learning institution, then the block may be caused by a content filter running on the Chromebook.
