When the Centralized KVM Page Is Opened for the First Time, It Displays Nothing and Finally Times Out


When the centralized KVM page is opened for the first time, it displays nothing and eventually shows "Timeout. Click the link to access the page again."

The Java Console shows that the connection to the certificate verification website (such as OCSP) times out, as shown in Figure 6-4.

Figure 6-4 Connection attempt timeout

Possible Causes

If an MM910 version later than (U54) 5.57 is used, the JAR package for the KVM must be verified by an authority. Otherwise, the local PC cannot connect to the certificate verification website and the connection attempt times out.


  1. Ensure that the local PC can connect to the certificate verification website.
  2. Refresh the KVM page.
  3. Disable the digital signature check of the JAR package.
    1. Choose Start > Control Panel > Java.
    2. Click the Advanced tab, and select Do not check (not recommended) for Perform signed code certificate revocation checks on.
