Why Does the Session Page Fail to Load When I Log In to the Managed Host Using a Web Browser?

Symptoms

When a user attempts to log in to a managed resource in CBH, the O&M session page fails to load.

Possible Causes

The browser blocks the request or the system SSL certificate has expired.

Removing the Browser Blocking Restrictions

1. Check whether the browser is a recommended one.

   Table 1 Recommended browsers

   Browser	Version
   Edge	44 or later
   Google Chrome	52.0 or later
   Safari	10 or later
   Mozilla Firefox	50.0 or later

2. Open the browser, view the messages in the upper right corner of the address bar, and check whether the page is blocked by the browser.
3. Disable the pop-up window blocking.
   • Use Google Chrome browser as an example. In the Windows OS, select Edit Popup Blocker Options and deselect Block Pop-up windows to log in to the resource.

Updating the System SSL Certificate

A CBH system is configured with a secure self-issued certificate by default. There are restrictions on the authentication protection scope and time limit of the self-issued certificate. To better protect your CBH system, you can replace the self-issued certificate with your own SSL certificate. However, if the self-issued certificate expires or fails to pass the security scanning, update it to ensure the CBH system security.
