Technische Artikel ID: KB89236

Umgebung

McAfee Active Response (MAR) 2.x

Problem

The MAR Workspace page fails to load, and displays the error:

An error has occurred.

In the MAR Heath Status page, the Cloud Storage & Services section displays the error:

Cloud Storage & Services - Status: Not Available

Or, the Workspace does not show any data fetched from the Cloud.

Ursache

A proxy or firewall is changing the McAfee Cloud Bridge certificate. When the proxy or firewall performs SSL decryption and inspection, it changes the certificate that McAfee Cloud Bridge uses to make a successful connection.

Lösung

View the Cloud Bridge settings. Click Configuration, and then verify that the Status shows as Linked. If the McAfee Cloud Bridge Status is Not Linked, see KB89062.

Verify that SSL decryption or inspection is occurring and obtain the details of the certificate being substituted, by inspecting the certificate:

Open a Chrome or Mozilla Firefox browser window, and go to the following URL:
https://provision.manage.mcafee.com/provision/

NOTE: You can’t use Internet Explorer.
View the certificate:
- In Chrome:
  1. After you access the URL, press F12 to open Developer Tools.
  2. Click the Security tab, and select View Certificate.
  3. In the pop-up menu, click Details.
- In Firefox:
  1. After you access the URL, click the lock to the left of the URL.
  2. Click More information, Security, View Certificate.
  3. In the pop-up menu, click Details.
Inspect the Issuer of the certificate and check if the certificate contains the entry:

CN = McAfee OV SSL CA 2
O = McAfee, Inc.
L = Santa Clara
S = CA
C = US

If you see any other certificate entry, an incorrect certificate causes the issue. Go to Resolve the issue below.
If you see the entry above, you have the correct certificate, but you have another issue. Contact Technical Support.
To contact Technical Support, log on to the ServicePortal and go to the Create a Service Request page at https://support.mcafee.com/ServicePortal/faces/serviceRequests/createSR:
- If you are a registered user, type your User Id and Password, and then click Log In.
- If you are not a registered user, click Register and complete the required fields. Your password and logon instructions will be emailed to you.

Resolve the issue:

Make a note of the incorrect certificate that displayed.
Work with your network team to determine and correct the source of the SSL inspection or decryption of the McAfee Cloud Bridge connection.

NOTE: The issuer of the certificate offers guidance regarding what device or appliance is changing the certificate.
After you resolve the SSL decryption or inspection issue, repeat the browser test to confirm that the correct certificate displays.
Verify that the MAR Workspace page loads properly and the Cloud Storage & Services section of the MAR Heath Status page shows Available.
