Troubleshooting Arcserve UDP Agent (Windows) › When fail to import VMware VMs from vCenter, the error message is “The application cannot communicate with the ESX/vCenter server. Verify that the login credentials are correct and the server is online”.

When fail to import VMware VMs from vCenter, the error message is “The application cannot communicate with the ESX/vCenter server. Verify that the login credentials are correct and the server is online”.

Symptom

In fact the vCenter server works well, and it can be connected with both the browser and vSpahere client. In ARCAPP.log file of Arcserve UDP Console server, the error message is as follows:

com.sun.xml.ws.client.ClientTransportException: HTTP transport error: javax.net.ssl.SSLHandshakeException: java.security.cert.CertificateException: Certificates does not conform to algorithm constraints

But when you change the integer value of jdk.certpath.disabledAlgorithms in the file “c:\Program Files\Arcserve\Unified Data Protection\Management\TOMCAT\JRE\lib\security\java.security” to a smaller number (such as 512), it can connect to the same vCenter server by Arcserve UDP.

Cause:

vCenter Server has a certificate with a public key length less than 1024 bits, while the Arcserve UDP console (in fact JRE in Arcserve UDP) requires that any certificate used by a vCenter Server has a public key length of at least 1024 bits.

Solution

Generate a new certificate for the vCenter Server. Ensure that the new certificate has a public key that is greater than 1024 bits in size.
