Trying to connect to Tridion via ECL WCF api but getting permission issue. Here is my code:

EndpointAddress eclServiceEndpoint = new EndpointAddress("net.tcp://localhoast:2660/ExternalContentLibrary/2012/netTcp");
NetTcpBinding binding = new NetTcpBinding
    MaxReceivedMessageSize = 2147483647,
    ReaderQuotas = new XmlDictionaryReaderQuotas
        MaxStringContentLength = 2147483647,
        MaxArrayLength = 2147483647
// ecl service client
var eclServiceClient = new SessionAwareEclServiceClient(binding, eclServiceEndpoint);

I am getting a permission error in the last line. I have added impersonation user to server, restarted COM+ services and IIS but nothing works.

What am I doing wrong? We are using Celum as ECL and we have DXA 1.9 (Web 8.5).

Welcome to Tridion stack exchange.

Have you added impersonation user to CM configuration?

Here is the SDL Docs link to do that.

  • yes, I think he did so because he added it in comment.

    Hello, I found the solution for my problem. I forgot to restart SDL Service Host service after I added my username as Impersonation user, so the change was not taken. Thanks for your time.

    In that case, please post your comment as an answer and 'accept' it so the question becomes closed
