It mentions some connection list.
Are you sure this is not some company/network/firewall/browser related feature?
Which tool is giving this message? Is it the web interface towards the Database explorer/query editor?
Please provide information about the steps you have taken, the guide you follow, and the errors you receive. Which security feature are you describing?
