Can't open a LearningGrids resource in DocsPlus
While browsing LearningGrids in the DocsPlus Explorer, you click a resource's Run Now button but nothing happens.
You may receive an error message saying Unsupported File Type or that the file is corrupted.
Firewalls or proxy servers can block DocsPlus from downloading resources.
If your computer has a firewall installed, try adding this location to the firewall's exclusion list:
32-bit Windows - C:\Program Files\Crick Software\DocsPlus
64-bit Windows - C:\Program Files (x86)\Crick Software\DocsPlus
If you're unsure how to do this, or it doesn't solve the issue, please pass the following information to your IT Support.
Alternatively, access www.learninggrids.com using a web browser instead of DocsPlus. You can download the resource as a file, which you can then open in DocsPlus.
Information for IT Support
DocsPlus uses the computer's proxy settings to connect to the Internet. When a user downloads a resource from LearningGrids, the following happens:
- User clicks the Run Now button.
- DocsPlus requests the page https://www.learninggrids.com/ResourceStream.aspx?... (the exact URL depends on the resource).
- The web server responds with the resource file. In the response, the web server sets the MIME content type in the HTTP header, so the computer can determine how to use the file.
Add LearningGrids.com to your list of safe sites
If your firewall / proxy allows you to specify safe websites, add a rule to allow www.learninggrids.com.
If it only supports IP addresses: 18.104.22.168 and 22.214.171.124
If you need to specify protocols: HTTP (Port 80) and HTTPS (Port 443)
Disable "Do not save encrypted pages to disk"
This Internet Explorer setting is disabled by default. If enabled, it prevents files being downloaded over HTTPS, leaving DocsPlus unable to download resources from LearningGrids.
The setting can be found in the Advanced tab of Internet Options in Control Panel. The corresponding Group Policy is:
User Configuration - Windows Settings - Administrative Templates - Windows Components - Internet Explorer - Internet Control Panel - Advanced Page - "Do not save encrypted pages to disk"
Allow the following MIME types
Ensure the following MIME types are allowed through the firewall / proxy via HTTPS (and SMTP if you wish to allow these files to be emailed):
If the firewall / proxy supports it, we recommend adding the wildcard:
Alternatively, add each MIME type individually:
