We have only a handful of users that are getting disconnects after very random times, 10 minutes, 30 minutes, etc. If I set them to use pure SSL, they do not get disconnected. Anybody have this and what did they do to fix this. I have been chasing this for awhile now.
I would suggest opening a ticket with JTAC as we would need to review the NC client logs along with the IVE (event, user access and admin) logs to narrow down the issue.
My educated guess would be there is something in the route between the NC client and IVE that is resetting or dropping the UDP port (4500). We've seen this in the past when a personal router or firewall have a UDP time out set to low and started dropping connections. If possible, you can test out this theory by having the same user connect to the IVE through a different median like by-pass their personal router by connecting directly to the modem. This may help narrow down the issue from the end-user side.
