Office 365 will not activate when browsers are set to go through CyBlock

Category: Administration

If you are attempting to activate your Office 365 products through CyBlock and are unsuccessful, please try the following steps:

  1. In your CyBlock interface, go to User Management – Authentication.
  2. Click the Bypass tab.
  3. Click the green plus icon to add a new bypass entry.
  4. Add the following two URLs to bypass authentication:

– For URL or Domain, enter *.microsoftonline.com (with asterisk). For User-Agent, enter * (asterisk).

– For URL or Domain, enter *.live.com (with asterisk). For User-Agent, enter * (asterisk).

This should now allow your products to activate properly.

Web page or application will not load through CyBlock

Category: Administration

When a Web page or application will not load, there is most likely a few possible things that could be in play. Many issues have to do with the site or content delivery network being blocked from another categorized site that is not part of the site you are trying to get to. Below are the troubleshooting steps:

  1. Is there a site being blocked by CyBlock?
    • Check the Real-Time Web Monitor for the IP address of the user in question, and also make sure you have the Authentication Challenge Requests (407) and the Authentication Type check boxes selected.
    • Do you see any URLs that appear in red? These URLs are blocked URLs and must be allowed in one of your filter policies or white lists.
  1. If there are no blocked sites, check for any 407s in the Real-Time Monitor.
    • Copy these URLs with 407s and add them to the User Management – Authentication – Bypass tab. Add the URL in question, with User Agent *.
    • Does the site now load?
  1.  If you have tried the above with still no success, try using another browser such as Firefox or Chrome.
    • Does it work with another browser other than Internet Explorer?
    • If it works with other browsers, it may be the Internet Explorer Compatibility Mode.
    • Open Internet Explorer, go to Tools – Compatibility View settings, and unselect the Display intranet sites in Compatibility View check box.
    • Does the Web page or application now load?

How to troubleshoot Web sites that do not authenticate

Category: Administration, Authentication Manager

This applies to CyBlock Software, CyBlock Appliance, and CyBlock Cloud.

If you have troublesome Web applications that fail to authenticate, you can turn off authentication for that specific IP address to determine if it is an authentication problem.

  1. Go to User Management – Authentication.
  2. On the Rules tab, create a rule as follows:
    • For the network definition, select IP Address/Subnet.
    • For the type of authentication, select Disabled.
    • Enter the IP address of the computer that is experiencing an issue.
    • Add the rule.
  3. Try to access the site again.

If the test is successful, that is, you are able to get to the site, the problem is authentication, and you can add the URL to the Bypassed list in the Authentication Manager.

If the test is unsuccessful, the issue is not authentication, but proxying/filtering. Contact Technical Support for assistance.

For CyBlock Cloud, customers will need to contact Technical Support to have troublesome URLs added to the Bypassed list.
