Failed initializing the External Content Library with id mm

Question

I know this is probably asked in a previous thread but I'm getting an issue integrating fredhopper and SDL media manager with Tridion 2013 SP1

The code was running previously and suddenly it stop working today:

Failed initializing the External Content Library with id mm. One or more errors occurred. One or more errors occurred. No External Content Library provider with the name SDL Media Manager is available.

StackTrace Information Details: at Tridion.ExternalContentLibrary.DomainModel.MountPoint.get_ContentLibraryContext() at Tridion.ExternalContentLibrary.Service.EclService2012.GetList(String parentItemId, Int32 pageIndex, EclItemTypes itemTypes, IEnumerable`1 basedOnSchema) at SyncInvokeGetList(Object , Object[] , Object[] ) at System.ServiceModel.Dispatcher.SyncMethodInvoker.Invoke(Object instance, Object[] inputs, Object[]& outputs) at Tridion.ExternalContentLibrary.Service.TransactionSupportInvoker.Invoke(Object instance, Object[] inputs, Object[]& outputs) at System.ServiceModel.Dispatcher.DispatchOperationRuntime.InvokeBegin(MessageRpc& rpc) at System.ServiceModel.Dispatcher.ImmutableDispatchRuntime.ProcessMessage5(MessageRpc& rpc) at System.ServiceModel.Dispatcher.ImmutableDispatchRuntime.ProcessMessage31(MessageRpc& rpc) at System.ServiceModel.Dispatcher.MessageRpc.Process(Boolean isOperationContextSet)

Is there any configuration that I am missing due to which I am getting this error?

My Media Manager mount point configuration is-

  <ServiceEndPointAddress>[Hidden]</ServiceEndPointAddress>

  <ServiceCertificate storeName="My" storeLocation="LocalMachine" findType="FindByThumbPrint" findValue=[Hidden] />
  <StubFolders>

    <StubFolder id="tcm:4-101-2" />
  </StubFolders>

  <PrivilegedUserName>[hidden]\MTSUser</PrivilegedUserName>
  <EnableUpload administrators="true">

  </EnableUpload>
  <DistributionTypes>

  </DistributionTypes>
</MountPoint>

Answer 1

If it was running before and not anymore now, and you didn't change anything in the configuration just before it stopped working, then the configuration is fine.

My guess is something happened to the ability of the CMS connecting to the service end point address. Which could be several things:

1. connection issues somewhere between the CMS and the service
2. firewall rules changed
3. certificate expired, revoked or changed (on the server)
4. service down

Answer 2

I was also facing the same type of issue and after spending some good amount of time I found that in my visual studio product, the reference dll of the Tridion ECL was set to true for Copy Local property. It was creating a local copy and was referencing this local dll instead of the global one. After setting copy local to false it started working for me.
