I am running the Host on a computer with Windows Server 2008 R2. Both Viewer and Host are version 220.127.116.11. When I connect to the Host, I am able to see the screen, and send CTRL-ALT-DEL. I am also able to move the mouse cursor, and it recognizes mouse clicks. However, when I type on the keyboard (to enter the password) nothing happens on the Host side. On earlier version (not sure which), I was able to control this computer without problem.
When I first posted this, I had not rebooted after updating the Host software. I then rebooted it, and still had the problem. However, when I just tried it, it is now working. Not sure how to explain that. Perhaps I got confused, and did not actually try previously - after the reboot. Perhaps something is intermittent.
If it happens again, I will pursue further.
In answer to your other questions:
I was trying to enter the password on the Windows login (lock) screen. It recognized CTRL-ALT-DEL, the Cancel button, and the password enter arrow button. It did not recognize keyboard input, or clicking on the ease-of-access icon.
This server is running Webroot Secure Anywhere. If the problem should recur, I'll try disabling that, and see if it makes a difference.
I've seen exactly this issue come up twice in the last week (running v 7.x viewer on Windows Server 2019): mouse works, keyboard ignored completely. Definitely not using Webroot anything (Bitdefender is our AV of choice).
Could you please double-check if the remote Host is updated to the latest version 18.104.22.168 as well? In case if Host is not updated to the same version as Viewer please try updating it and see if this helps to resolve the issue as the version mismatch might lead to performance issues or some features not working.
Yes, issue still persisting on an updated install. Switching to RDP works better on the machine it's enabled on, so I'll be using that in future for most situations, but for freshly remote installed PCs I need to do some setup first, so still need the remote desktop to work occasionally :(
