UCWA: Receiving status code 499 during token request

Question

I am trying to work through the examples in the UCWA documentation, but I cannot authenticate a user.

Specifically, I can get through the following steps:

1. GET https://lyncdiscover.mydomain.net/ (or lyncdiscoverinternal.mydomain.net, same result either way)

• Response Code: 200

2. GET: https://lync.mydomain.net/Autodiscover/AutodiscoverService.svc/root/oauth/user?originalDomain=mydomain.net

• Response Code 401

3. POST: https://lync.mydomain.net/WebTicket/oauthtoken

• Response Code 499, "The custom error module does not recognize this error"

Any suggestions as to how I can debug this?

Answer 1

What request are you issuing to receive a 499 response?

Answer 2

Were you able to find a resolution for this issue ? I'm also having the same problem ... 

Answer 3

Collect WebInfrastructure and UCWA tracing from your front end, and review to see where the 499 error is coming from.
