    Good afternoon, I was hoping someone could give me a clue to solve my Skype Edge server implementation issue.  I recently setup a skype 4 business edge server and I'm trying to get a client connected to it.  All the DNS entries seem to resolve and I ran a netstat -n and I can see the client come over port 5061 and with a SYN_RECEIVED.  I've tried to go through the CsCLSLogs and look through the sip stack but I don't see anything related to the connection just internal clients trying to reach other domains that I'm not federated with.  I went and looked through the Skype 4 business client log on the external client and I just get a "ONEABLE_FAIL_SERVER_NOT_REACHABLE.  It discovers the server on port 443 just fine so I am kind of at a loss where to check next.  

    If someone could point me in remotely the right direction for logs or something else to look at I would be most grateful.

    Thanks

    Also here's the client logs

    Doing logon attempt with data:

       currState=LoggedOut

       sipUri=sip@domain.com

       server=<auto-discovered name>, internal

    Hi 

    The best approach is to use Connectivity analyzer and see the results of the tests

    https://www.microsoft.com/en-us/download/details.aspx?id=36535

    Based on the result we would be able to identify the issue with the DNS records ,certificates etc..

    Thanks for the reply, it keeps complaining about lyncdiscover.domain.com can't be resolved.   I thought you only needed a reverse proxy for mobility clients and additonal functionality?  I was thinking about putting the reverse proxy into place but currently just have an edge server.
