I installed expressway for collaboration edge, and it works fine for Jabber for Windows.
But when I tried Jabber for Mac (9.6), the phone services and voicemail are connected, but not the IM service. Same thing happens for Jabber for iPhone and iPad.
When I checked the event log, it says
tvcs: Event="Inbound TLS Negotiation Error" Detail="No SSL error available, probably remote disconnect"
By the way, I am using self-signed certificates following the VCS certificate deployment guide and MRA deployment guide.
