I am experiencing this - the remote machine is online via a wired Ethernet connection to the router with a 500Mbps fiber connection. The machine running the viewer is online via a 100Mbps fiber connection at my location. I am connecting via internet ID. This is not a new issue for me, as it has been happening for months - but reading this thread it should be fixed now?
My connection has dropped repeatedly today, and the viewer keeps notifying me every few minutes the machine is online. Sometimes, I cannot connect - the viewer will claim the machine is online. I click to connect, enter my password and wait - only for it to flash to being offline, followed seconds later by it claiming to be online again. When I do connect, some times the connection lasts only a few seconds. Other times, I stay connected for a few minutes - 20 was the best I have seen today. The internet connections at both locations are very reliable. I am running 188.8.131.52 on host and viewer Is there a way I can download an older copy of the viewer, as some have stated running an older version fixes this issue? I have logging enabled on both ends - according to the logs for the viewer there is a stack trace from a crash every few minutes.
