I have my UCCX servers setup in HA and certs have been signed for all services. I am attempting to get Finesse 12.5 Desktop Chat going and currently I have set my Desktop Chat Server to both of my IM & Presence servers. All seems to be working with Finesse except the Desktop Chat service. I will login a user to Finesse then have that user attempt to login to Desktop Chat. The login appears to be successful and displays a pop-up screen to accept the certificates for both of my IM&P servers (The ones I defined as the Desktop Chat Servers in Finesse Administration). When I click the links to accept those certificates (link = https://imp1.voip.domain.abc:5082/httpbinding & https://imp2.voip.domain.abc:5082/httpbinding ) and I continuously receive an error "Secure Connection Failed: An error occurred during a connection to imp1.voip.domain.abc:5280.PR_END_OF_FILE_ERROR." This happens for both links. This seems like a certificate problem but I have signed certs on all UC platforms with the RootCA and IssuingCA uploaded on each host via the respective service-trust as needed. Has anyone ran into this problem with Desktop Chat Server?
