IOS App - Cannot connect to server RRS feed

  • Question

  • Hi,

    We're deploying our first S4B installation and clients can connect to our S4B setup.. The only problem we've is that mobile users can't connect to the server with the S4B app installed on their phone. 
    They Always receive the error 'Cannot connect to server', after 2 seconds of clicking the sign-in button very strange !

    The lyncdiscover.domain cname record exists and point to the WAF reverse proxy which points on his way to the FE server on port 4443 to give them autodiscover details..

    I guess we miss something essential..

    Your help is appreciated !

    If you use https://lyncdiscover.yourdomain you will get a configuration file back?

    Please use public certificate to reverse proxy.
