Lync connectivity analyser loop and dump

We had an issue with certificates on Lync frontend, as a result the Lync connectivity analyser (a program, not the online one) was trying to reach WebTicket and after rejection was doing that in circles until it dums out.

The error:

Cookie  found in autodiscover response: StatusCode: 401, ReasonPhrase: 'Unauthorized', Version: 1.1, Content: System.Net.Http.StreamContent, Headers:
  Connection: Keep-Alive
  X-Ms-diagnostics: 28032;source="xxx";reason="The web ticket is invalid.";faultcode="wsse:InvalidSecurityToken"
  X-MS-WebTicketURL: https://xxxxx/WebTicket/WebTicketService.svc
  X-MS-WebTicketSupported: cwt,saml

  Content-Length: 4966
  Content-Type: text/html; charset=utf-8

It seems that after some test with Bindings in IIS, the certificates were not aligned. 

The soltion is to re- request  Lync frontend default certificate and make sure we get one certificate for all 3 services (except obviously OAuth).
