Symptoms

Affected Products:

  • Dell Data Protection | Virtual Edition

Affected Versions:

  • v9.2 and Earlier

Client Security Framework (agent) policies do not pull properly. This is due to TLS communication to the backend server.

Cause

This error is typically linked to Dell Data Protection | Virtual Edition v9.2 and earlier, where the core server could only talk on TLS 1.0. Newer versions (9.3 and later) have a new service that is named Core HA Proxy and it can communicate up to TLS 1.2.

When the below errors are seen, an upgrade is necessary to resolve the issue:

2016.04.05 16:09:09 I Comm : opening connection to "https://<server.domain.com>:8888/agent"
2016.04.05 16:09:11 E Comm : communication exception - An error occurred while making the HTTP request to https://<server.domain>.com:8888/agent. This could be due to the fact that the server certificate is not configured properly with HTTP.SYS in the HTTPS case. This could also be caused by a mismatch of the security binding between the client and the server.: The underlying connection was closed: An unexpected error occurred on a send.
2016.04.05 16:09:11 I Comm : next contact with server scheduled for 4/5/2016 4:10:11 PM
2016.04.05 16:10:11 I Comm : opening connection to "https://<server.domain.com>:8888/agentv2"
2016.04.05 16:10:12 E Comm : communication exception - An error occurred while making the HTTP request to https://<server.domain.com>:8888/agentv2. This could be due to the fact that the server certificate is not configured properly with HTTP.SYS in the HTTPS case. This could also be caused by a mismatch of the security binding between the client and the server.: The underlying connection was closed: An unexpected error occurred on a send.
