Is it you can not connect or you cannot push your watch face to the device. If you can connect and generate a distributor certificate that is one thing if you can’t connect then here is what to do.
Not being able to connect has became a more common problem with the newer versions of Tizen 4. For the first time connection you have to acknowledge the RSA Key. However, it doesn’t stay very long and if you don’t allow it you will get the can’t connect error. Usually restarting your watch will force it to be displayed again but I found it took several tries and leaving it off for over a minute to force the RSA Encription acknolwedgement again.
Here is my rundown.
Go to Settings -> Gear info -> About device.
Tap on Software version 5 times. Then a confirmation pop up displayed once the Developer options is enabled.
Make sure Debugging is on in About Watch settings
Restart your watch make sure Debugging is on after the restart
Important …Restart your Phone too
If you’ve already tried to connect and failed restart your computer too.
For most people that can’t connect the problem has been allowing permissions watch for them on both the Watch and the Phone especially the RSA encryprion acknowledgement when you first try to connect. (it remembers after the first time and doesn’t display again, even if you don’t accept it)
BE SURE YOUR ETHERNET CABLE IS UNPLUGGED OR THE ADAPTOR IS DISABLED it isn’t enough to just be connected to the WiFi on your PC
You need to connect the Watch to the same network as the Computer WiFi Modern Modems have 2.4 and 5 Ghz bands you may need to have the PC connected to the 2.4 network.
I prefer to use SDBoverBT method with USB cable from your phone to the computer I like this because it eliminates firewall problems. If you need to use that let me know.
For Mac users it is reported that opening the WiFi settings on the watch and forget network and reset it allows GWD to find the watch where it previously couldn’t
Hope these help, it does work but if you don’t see the RSA acknowledgement after a few tries you probably disallowed it. more on that too.
