Could you please elaborate a bit more on the issue, namely, on what step the remote screen and input are locked? Does the issue occur at disconnect or when you just connect to the remote Host machine? It would be helpful if you could also provide us some screenshots.
It happened as soon as I was on the remote screen.
I finally got in my car yesterday, drove 35 miles to my office, where the host computer is, saw that the computer itself froze, shut it off, booted up again and got in from my iphone.
As of now it is up. Using it may be moot for the time being since we are having a storm with high winds and our lights are flickering.
Separate problem- while I was in the office I tried to set up a backup computer, running Windows 10 professional as a host. I changed that computer's settings so that it would allow incoming and also to not go to sleep. It worked while I was in the office but by the time I got home it appeared as offline/unknown.
Any quick solutions other than going back to the office, which is not an option at this time.
As for the second laptop - could you please double check if the remote Host is visible as online if you add it as a connection to some other Viewer in another network (for example, you can use Portable Viewer in a mobile network)? If the Host's status is offline in another network as well - then, unfortunately, this might mean there are connectivity issues on the remote Host machine, rather than on the Viewer's side.
It is a desktop and I used the IP instead of an internet ID. That shouldn't matter. Tried accessing using an iphone with a wi-fi network. Didn't work. I suspect that there is a problem at the host side that requires changing a setting. Thanks for the help though.
