title: SOAP Login error for some Acumatica instances
body: <p>Hello I have a C# tool that imports data into one of our custom forms in Acumatica.  It logins into the URL and imports data in batches.  It works fine for the most part, but we've run into one client whose instance we can't access.  I can call up their asmx page in the browser and everything looks fine but we get a strange error when the program invokes Login</p>
  <pre><code> Exception thrown: 'System.Web.Services.Protocols.SoapException' in System.Web.Services.dll
  An unhandled exception of type 'System.Web.Services.Protocols.SoapException' occurred in System.Web.Services.dll

  <p>Has anyone seen this error before? Here is my code snippet, it errors on Login.</p>
  <pre><code>_itemsScreen = new VendorItem.Screen();
          _itemsScreen.Url = url + &quot;/Soap/SW200014.asmx&quot;;
          _itemsScreen.EnableDecompression = true;
          _itemsScreen.CookieContainer = new System.Net.CookieContainer();
          _itemsScreen.Timeout = 3600000;
          _itemsScreen.Login(username, password);
  </code></pre>
