Hello Techies,

We have started getting the below error suddenly from last 2 hours.

"The plug-in execution failed because the Sandbox Client encountered an error during initialization." 

there were no changes made in recent past. the above issue comes only for the entity which has plugins registered against them.

Any help is appreciated!!

Thank you,

    Hi Ravi,

    Ours is on-premises, below error was getting logged.  Error stopped after iisreset and sandbox restart. Looking for any possible root cause. (how to avoid this in future?) 

    The Sandbox SDK Listener failed to start.
 Source: w3wp.exe 
 Endpoint: net.tcp://localhost/CrmSandboxSdkListener-w3wp
 Error: System.ServiceModel.AddressAlreadyInUseException: The TransportManager failed to listen on the supplied URI using the NetTcpPortSharing service: the URI is already registered with the service.

    Thanks,

    Hi,

    If it is CRM Online then it is likely a sandbox service down for your org/ tenant. It should be fixed now. If not, reach out to MS Support.

    Hi Francesco,

    Sandbox service was down on that day. After we created a ticket , MS have started the service and everything started working as expected.

    1. Your are talking about last year, so please try to update reference to last sdk libraries and republish the plugin.
    2. If this doesnt work it might be a Microsoft issue and I would do the following:
      1. Try to debug to understand the right point where the plugin fails
      2. If there is no reason to fail, open a Ticket to MS

    Please let us know.
    Greetings
    Francesco
