Tableau Desktop reads the http_proxy environmental variable even though no HTTP_PROXY environmental variable is set.
msinfo32 shows no HTTP_PROXY  environmental variable.


  • Tableau Desktop 2022.1.1

Verify if the proxy is configured on the PC by running the command "netsh winhttp show proxy" from Command Prompt.

Consult the IT administrator/team to check if the proxy setting is required on the pc. 
You can reset the proxy setting with the command "netsh winhttp reset proxy" if it's not needed.


The proxy server setting (http_proxy environmental) added by WinHTTP is remaining on the PC and recognized by Tableau Desktop.
