  1. Hi
    I am facing issue when I am trying to connect salesforce.com by Informatica 9.1.

    Bellow error is showing

    Login Failed.Errorcode:[SOAP-ENV:Client] Reason:[Timeout].

    using Service URL:https://test.salesforce.com/services/Soap/u/23.0
    Also I have set proxydetails in C:\INFORMATICA\9.0.1\clients\PowerCenterClient\client\bin\pmsfdc.ini.


    Please can you let me know what is the resolution of this?


    1. Have the proxy server details set in your Internet Explorer.

      • Tools > Internet Options > Connections > LAN Settings > Proxy Server.
      • And also add the proxy host name and ip in C:\Windows\System32\drivers\etc\hosts.ini file.

      Please go through my post about sales force.
