Error while checking for update: An error occured while sending the request

Answer / Solution

Check the event log of the Exchange Server Toolbox or the Windows Event Viewer under Windows Logs | Application for the following message:

"The request was aborted: Could not create SSL/TLS secure channel"

If this is present, you can fix the problem this way:

1. Press "Windows+R" and open "gpedit.msc".
2. Navigate to Computer Configuration | Administrative Templates | Network | SSL Configuration Settings
3. In the right pane, select "SSL Cipher Suite Order" and then click "Edit policy setting" in the center
4. Select "Enabled" in the new window

You can now copy the contents of the text box under Options | SSl Encryption Collections into a text document. Append the following keys at the end:

• TLS_DHE_RSA_WITH_AES_128_GCM_SHA256
• TLS_DHE_RSA_WITH_AES_256_GCM_SHA384

Follow the editing instructions in the right part of the window under "Help".

Then copy the text back into the text box and press "Apply" to save the settings. For the changes to be applied, you must restart the server.
