I am running a small home set up (less than 10 computers) with my own RU server for security, and this has been worked just fine. Until recently, when all of a sudden I cannot connect to and remote control one specific computer. I have tried just about "everything", including uninstalling the host and deleting all settings to start over a few times, but that makes no difference. I'm running the latest versions of all the RU software (host 22.214.171.124, viewer 126.96.36.199, and RU server 188.8.131.52), and I'm using "Custom Server Security" for all the computers. They are all configured exactly the same way and on the same physical LAN.
For the PC that Remote Utilities no longer can control the viewer will just show the usual message "Connecting to <computername>. Please, wait...
WHen I look at the log on the "host" computer, it looks like connections are established and ended normally, but the whole time the "viewer" window is just stuck with the "Connection to" message.
I can "Log on" to the computer in the "viewer" windows just fine so I see a miniature screen under "Logged on", I just cannot connect to it.
I didn't really think this could be a "missing display problem" as I havea few Intel NUC boxes with no display or display cable connected, and I can control them just fine. But not this relatively new AMD system with RTX 3070 graphics card, as soon as I unplug the HDMI cable I can no longer connect to it with Remote Utilities.
Now the whole purpose of using RU is to connect to such computers that are just left doing their things, with no need for an attached display.
Am I missing something here? RU is supposed to work even with no display connected to the "host", right?
How do I fix this issue so I can connect to the computer without having to have a display connected?
I did order a few of these "dummy HDMI plugs" that tricks the display card into believing that a display is attached, the kind that are usually used for "Mining rigs". But should that really be necessary?
