Resolution

You need to add path to PAC file (auto-configuration script) into defaultProxy setting of Web.config file of web service and into eWayTimer.exe.config.

<defaultProxy enabled="true" useDefaultCredentials="true">
    <proxy scriptLocation="http://proxy.example.com/proxy.pac" />
</defaultProxy>

After you make changes to the eWayTimer.exe.config file you have to restart eWayTimer service.

Configuration file eWayTimer.exe.config is inside bin directory of the Web Service. If the configuration file eWayTimer.exe.config does not exist, you have to create it:

<?xml version="1.0"?>
<configuration>
  <startup>
    <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.0"/>
  </startup>
  <system.net>
    <defaultProxy enabled="true" useDefaultCredentials="true"/>
  </system.net>
</configuration>
