Real vnc connect to listening9/3/2023 No network issues for a continuous period of 70 days. UPDATE: I have connected four rpi4s to a hub, and the hub uplink port with a wired connection to a Linksys Velop satellite node. I know that does not help right now if you can’t VNC or SSH into your system. This seems to help, but it occasionally goes down. I also run a cron job and script to check if the WiFi is down and reconnect. So.my suggestion is to connect your rpi to your router by cable, or to run 1-2 backup rpi (could use zero’s for this) on a cheap Ethernet hub so you can reboot if one goes down. (I am running a Velops mesh system with reserved WiFi IP addresses for each pi). I suspect it is due to instability in the WiFi daemon in Raspbian Buster, as the hardwired connection never drops. I have been troubleshooting this for a couple of months, and don’t yet have a definitive answer. After that, we need to check If we have disabled cloud connections in VNC Server’s Options dialog, under the Connections heading. I know the rpi4 itself is still running as I can ssh to it via a wired connection (all the rpi4s are on both WiFi and a separate hardwired Ethernet subnet via an independent router). The remote computer is not connected to the Internet 2. I know RealVNC is up, because I can reach the other 3. RealVNC seems to go down somewhat randomly on the four rpis, but much less frequently on the one running the python routine. I have a 3 x rpi4 cluster and a single rpi4 running a python routine to monitor a wine cabinet. I have the same problem, and I don’t think it is the RealVNC servers, but rather the WiFi connection dropping and not restarting. At this point I think I might just be screwed, so if anyone could explain in the comments why VNC likes to commit death when I need it not to (maybe I need to have my pi automatically reboot daily?) that would still help. Other internet-connected features on the pi were still working, although the only one I have access to has crashed due to (I assume) unfinished code changes.ĭoes anyone have any ideas why this happened, or how to remotely troubleshoot this with no portforwarding or SSH? I cannot try rebooting or doing anything that uses keyboard+mouse because I am 100 miles away and cannot return.Ĭlarification: The remote place IS my home and the only key-holders closer to my home than me are computer illiterate. The installation program then establishes a connection with the listening VNC viewer using the specified system host name and port number. A couple of attempts later, the connection failed with a message: "VNC Server is not currently listening for Cloud connections." The client (running on windows) suddenly froze, like it often does, so I disconnected and tried to re-connect, only to find it refused. The listening viewer will remain in this dormant state until a remote. I'm currently 100 miles away from said Raspberry Pi, and it's suddenly stopped listening for cloud connections through no intervention of my own. ii Select the RealVNC entry, then VNC Viewer 4 and finally select Run VNC Viewer.
