Trouble using OCS due to server connectivity

Asked By 0 points N/A Posted on -

We would like to use OCS for our organization since CA certifications were already expired. So we have to renew it again. But we are already having troubles on using OCS. When people try to exchange messages to other people within the organization, a warning message appears. Together with the symbol “!,” the message goes like this; “Some calls to and from people outside of your corporate network may not connect due to server connectivity problems.  Try signing out and back in, contact an admin…” One more thing, a person said that it can’t totally access the Office Communicator at all on his laptop. An error message like this occurred; “Cannot Sign in because the server is temporarily unavailable. If the problem persists, contact your system administrator.” Right now, we are using OCS Server, Conferencing Edge and a Communicator Web. I would like to ask for assistance to unravel this problem. I’m not yet familiarize on the functions and features of this software but you can give me instructions on it. I’m good at following instructions.

Trouble using OCS due to server connectivity


Hallo Bill Clifford,

This kind of error is occurring possible because there is mismatch of what is anticipated by the front end server that you are using and what you are presenting to it. In your case it could be as a result of the internal interface that is on the edge server using the public certificate with its name in the following format, and therefore when the server in the front end connects to the edge server the name that is issued is xxx-edge-01.someDomain.local.

To resolve that error, you will need to assign the internal certificate, and make sure that the certificate has not reached its expiry date yet. See if the error goes away when you change the certificate.

Hope this helps.
