Hello

I have a program that runs 2 lines to connect to CRM Online. In my pc it works well, I have also tried in a server and it works well. The problem is that the same code does not work on the client's server and I do not know what else to look at. Any ideas? Can it be the client's proxy?

This is my code.

ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;
CrmServiceClient conn = new Microsoft.Xrm.Tooling.Connector.CrmServiceClient(ConfigurationManager.ConnectionStrings["crmonline"].ConnectionString);

_orgService = (IOrganizationService)conn.OrganizationWebProxyClient != null ? (IOrganizationService)conn.OrganizationWebProxyClient : (IOrganizationService)conn.OrganizationServiceProxy;

=> conn.LastCrmError; (unable to Login to Dynamics CRMOrganizationWebProxyClient)

Thank you very much.

Hi Enrique,

Seems the problem is related to network proxy and firewall. If you enable any proxy in the client network try to disable first and check.

Also check .net framework version in client machine. It's should be 4.6 or above.
