AWS-999 Unable to connect to Respondus Server (AWS)
Posted by Respondus Support
The above error indicates your computer and/or network is blocking access to Respondus servers hosted on AWS (Amazon Web Services). Until the block is removed, you will not be permitted to proceed.
If you open LockDown Browser, navigate to a course and don't see the "Help Center" button in the LockDown Browser toolbar, this is further evidence that a block to our servers is in place.
In most cases, the block exists in overly aggressive anti-virus or firewall software running on your computer.
Steps you can take:
1) The following are the servers that LockDown Browser must have access to. Whitelisting these in your anti-virus or firewall software might help:
Please contact the manufacturer of your security software in order to determine how to whitelist domains. Respondus Support cannot assist you with this.
2) If the whitelisting does not help, temporarily disabling (or uninstalling) your anti-virus or firewall software may help. If using Windows, you may also want to disable Windows Defender. Be sure to re-enable the software after your exam is finished.
3) If using a Windows computer, be sure that the TLS 1.2 protocol is enabled. It's common for older Windows 7 operating systems to have this setting disabled.
To check this, go to Control Panel > Network and Internet >Internet Options and select the "advanced" tab. Scroll down in the list and you'll see and entry for TLS 1.2. If not checked, do so and then click "apply" and then "ok".
4) If the above steps do not solve the problem, it's possible the block exists in the network you are using. Try using various networks to see if that helps.
Removing a block falls outside the scope of Respondus Technical Support. If the above steps do not help, you will likely need to use a different computer and/or network to take your exam.
