Using PageStoreService.asmx I'm trying to get a page with id = "1000000002__Article". The page is stored with a custom page provider "Article" and PageReference.RemoteSite is set to "Article". The error below persists and it looks like no RemoteSite is passed over SOAP.

System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.ServiceModel.FaultException: System.Web.Services.Protocols.SoapException: Server was unable to process request. ---> EPiServer.Core.PageNotFoundException: Page 1000000002 was not found at EPiServer.DataAccess.PageLoadDB.LoadPageInternal(PageReference pageLink, Int32 languageBranchId, IDataReader reader) at EPiServer.DataAccess.PageLoadDB.<>c__DisplayClass1.b__0() at EPiServer.DataAccess.DataAccessBase.<>c__DisplayClass1`1.b__0() at EPiServer.DataAccess.DatabaseFactory.Execute[TResult](Action`1 method) at EPiServer.DataAccess.DataAccessBase.Execute[TResult](Action`1 action) at EPiServer.DataAccess.PageLoadDB.LoadPage(PageReference pageLink, Int32 languageBranchID) at EPiServer.LocalPageProvider.GetLocalPage(PageReference pageLink, ILanguageSelector selector) at EPiServer.Core.PageProviderBase.<>c__DisplayClass4.b__3() at EPiServer.Core.OptimisticCache`1.Read(String cacheKey, ReadAndCacheObject`1 readAndCacheObject) at EPiServer.Core.PageProviderBase.GetPageInternal(PageReference pageLink, ILanguageSelector selector) at EPiServer.Core.PageProviderBase.GetPage(PageReference pageLink, ILanguageSelector selector) at EPiServer.DataFactory.GetPage(PageReference pageLink, ILanguageSelector selector) at EPiServer.WebServices.PageStoreService.GetPage(PageReference pageLink, LanguageSelector selector, AccessLevel access)
