How to Configure WinHTTP Proxy for Veeam Components
Purpose
This article documents how to configure WinHTTP Proxy settings for Veeam components in environments where the software must use an HTTP proxy to access the internet.
Solution
Known Limitation: WinHTTP does not support proxy authentication.
System-Wide Configuration
This change is system-wide and will affect all applications that use WinHTTP, including other third-party or Windows services that use WinHTTP (e.g., Windows Update).
Check Current WinHTTP Proxy Settings
This command will disaplay the current WinHTTP settings:
netsh winhttp show proxySet WinHTTP Proxy Settings
This command can be used to set a WinHTTP proxy:
netsh winhttp set proxy proxy-server="<proxy>:<port>"Note: Replace <proxy> and <port> in quotes with the actual proxy server's hostname or IP and the port it uses. For example this command would set the proxy for all protocols to use 192.168.111.111 port 8080:
netsh winhttp set proxy proxy-server="192.168.111.111:8080"
Reset WinHTTP Proxy
This command can be used to reset the WinHTTP settings back to default (no proxy).
netsh winhttp reset proxy
