Lifecycle Services System Diagnostic Service - Proxy Authentication Required

(0) ShareShare
ReportReport
Posted on by

I'm trying to install the System Diagnostic Service. I can generate and upload the certificate with no problems but when I click Next after uploading the certificate I get the following error:

"Specify the valid certificate to authenticate Microsoft Dynamics Lifecycle Services System Diagnostic Service"

The install log in appdata for the installer contains the following error:

Exception details: System.ServiceModel.EndpointNotFoundException: There was no endpoint listening at diagservice.lcs.dynamics.com/externalservices.svc that could accept the message. This is often caused by an incorrect address or SOAP action. See InnerException, if present, for more details. ---> System.Net.WebException: The remote server returned an error: (407) Proxy Authentication Required.

I have set the proxy settings in Setup.config but this doesn't seem to make any difference - I suspect I am doing something wrong here. I can browse to diagservice.lcs.dynamics.com/externalservices.svc with internet explorer using auto detect proxy settings - or with the proxy settings I have specified in setup.config.

I have read the following thread and tried everything there, however I think my problem is different: community.dynamics.com/.../122611.aspx

Any ideas?

    Hi Daniel!

    I know this is an old thread, but I just got the same error as you described. :)

    So, I just stopped the Diagnostic service and changed the service account to the same account as in AOS service. That's what did the trick for me.
