note Note:

This article applies to Endpoint Security, Bitdefender Endpoint Security Tools (for Windows and Linux) and Endpoint Security for Mac.

Errors Description

  • 1003: Could not resolve proxy
  • 1004: Could not connect to proxy or server
  • 1005: Could not authenticate to proxy or server

Possible Causes

  • The endpoint is not configured correctly to communicate over the internet through a proxy.
  • The endpoint cannot resolve the proxy due to a DNS issue.
  • There is no proxy configured in the Bitdefender policy.

Troubleshooting Steps

At first, ping the proxy hostname to check if it is resolved correctly.

In the GravityZone policy, go to General > Settings > Proxy Configuration and configure the proxy server used in your network for outside communication.
