Can't control ARD 3.8.5 clients using ARD 3.8 on 10.11

Recently upgraded my station and a few clients to 10.11.1 from 10.9.5

I use ARD 3.8 for various daily tasks. Push files, control the client stations for support etc.

The stations I haven't upgraded yet – running 10.9 & ARD client 3.8.4 I can control just fine,

but the stations upgraded to 10.11.1 & ARD client 3.8.5 I get the following message...

"Connection failed to “**********" Please make sure that Screen Sharing (in the Sharing section of System Preferences)
is enabled on the computer to which you are attempting to connect. Also make sure your network connection is working properly."

On the client machines I've toggled Remote Desktop on and off, for specific users and all users, turned screen sharing on etc, restarted.
Also tried over ethernet & wifi. Always the same message.
It looks like ARD 3.8 app on my station didn't get any sort of update after the 10.11.1 upgrade – it's still Version 3.8 (380A95) and Mac App Store says it's up to date.

Any advice would be appreciated. I'm not going to upgrade anymore stations to El Capitan until I Know I can control them with ARD.

Removed the machines and added them again to ARD.

I can remotely restart the machine, do reporting, copy a file, I just can't control or observe.

Any advice would be greatly appreciated.

Got it to work for all of my 10.11 Clients.

This is what I did;

– Turned off Remote management in Sharing in System Preferences

– Turned on Screen Sharing & enabled "Allow access for • All Users"

– Quit system preferences

– Reopened System Preferences & Sharing - turned off Screen Sharing

– Turned on Remote Management & enabled "Allow access for • All Users"

– In computer settings check "Anyone my request permission to control screen"

– Quit system preferences

Bit late to it but I've also found that "Observing" more than one at a time works fine and from there you can control easily. Silly bug but it's a work around.

This worked for me with 10.11.4 ARD and clients.

Thank you.

Same here. Observing clients running 3.8.5 from Remote Desktop 3.8 (380A95) wouldn't work. However I could still connect to individual clients by running the Screen Sharing app. The workaround of selecting more than one client at a time in Remote Desktop and observing the set works, but I'd like to figure out a better fix.

Problems here with 3.8.5, none of the proposed solutions work. In my case what does work is physically walking up to the computer using keyboard or mouse to get it to "come alive" again. See ARD Client 3.8.5 and headless server not reachable

This is only happening to the one machine I upgraded to 3.8.5 so I'm pretty sure that's to blame.
