Troubleshoot Bitdefender failed updates using Wireshark

Context

When your Bitdefender product cannot obtain product / signature updates from our Update Server, the Bitdefender Support Team may request a packet capture for troubleshooting the issue. For this purpose, we recommend using Wireshark, a free (open source) packet capture software broadly used for analyzing network traffic.

Issue

The Bitdefender Support Team usually requests a Wireshark capture for the following scenarios:

  • The endpoint or the relay server fail to retrieve updates from Bitdefender Update Server (upgrade.bitdefender.com) or from the local relay server with errors indicating that a content-filtering solution or a network firewall might be blocking or filtering the packets.

    For example, error code 1011, which indicates an IO time out in the Bitdefender product interface:

    Bitdefender Endpoint Security Tools - update error 1011

  • Excessive traffic bandwidth usage during the distribution of product / signature updates to target endpoints.
