CONNECTION Client never finishes signing in and the solution for this problem isn't working.

I want to use same connection client account in two different computer. I can use connection client in one computer but for other I have problem about signing in. I would like to ask you new method for solving the signing in problem. Because I have tried to do all the steps that is mentioned in this link;

https://communities.bentley.com/communities/other_communities/sign-in_assistance_and_web_services/w/wiki/43198/connection-client-never-finishes-signing-in

However I couldn't find System.Configuration.ConfigurationErrorsException string in the zip file. So I think there must be another reason for this problem. And also I have done health check and I found logging service and policy service errors.  

Thanks for your helping...
