Skype for Business persenting

Is this a local sfb to local sfb?
Or local sfb to federation users?
Or Lync 2013 to sfb?


If it is sfb to federated domains then try to allow the sip domain under SIP Federated Domain on your sfb server.
As per attachment... add new.

hello T Barlow,

  this is  from local SFB user to Local SFB.

Hi there, check ports 6891-6901 tcp on your public facing firewall.
those are the ports used for file sharing.

i make logging and found this

ms-diagnostics: 1058;reason="An error occurred routing on the remote client connection";winsock-code="10057(WSAENOTCONN)";winsock-info="The socket is no longer connected";Peer="my email",source="the edge server"

Sounds like a tls cert negotiation failure.
Try restarting SBS FE service\s and the Edge Access Service.

restart all service but still problem exist "error in transfer "

Have you checked your server event logs?

hello ,

 i checked event viewer from the front end and Pchat server  and didn't find any error

Alkholi i'd love to assist but this will be back and forth I need logs and info from UM and FE also
Windows event viewer (the lync\um server one) and skype for business tracing logs and anything related. I have created a email on my side so we can test.

Please email me at expertexchange236@gmail.com. Please send all the logs you can and I will see what I can find. Don't forget times that you  errors occurred so I can compare.

Screenshots of certificates on IIS and personal certificates.

Please export the logs to clearly labelled files for me. Tx

hello Barlow,


   i sent to you the logs.

Thanks Barlow very much for your support on team viewer , i am now  change all FE certificate , and  guide network team to open port 443 on the edge as they closed it by mistake. put still problem exist after some search, some people told that happened because i don't have a public Certificate. is this issue may cause the problem?

Hi there,

That's correct. You can issue your exchange provider cert or local ca public certificate used by exchange.

hello there,

  so you mean that i must buy an external Certificate , to transfer file from outside or may i used my internal certificate?
