Failed to fetch private key

[JRC326]

@mariotaku HI: My desktop OS is Win 11 ,LG TV is qned86sqa, WebOS & Developer Mode is updated to date. Just use developer account to log in Developer Mode, Dev Mode Status and Key server both turned on. Dev manager 1.11.16 installed. When I add device on Dev Manager, All 4 steps are checked. address & passphrase all entered which shows on tv. After "please wait" its shows "failed to fetch private key". "Please make sure key server in developer mode app is turned on during device setup" <--But I actually turned on the key server. Tried several times and can't figure it out. Need your help,Please!

Hi, how do you connect the PC and the TV to the network? Can you do a ping to the TV?

I think you got the point! I try two different ways to connect the PC and the TV with wire. the first way : living room network socket--wire--asus zenwifi xd5 router--wire--TV study room network socket--wire--PC In this way cause Failed to fetch private key. then second way: living room network socket--wire--TV study room network socket--wire--PC In this way I successfully add device on Dev Manager! but I need the router to launch wifi. So I think now the question is :How can I use the first connect way to use Dev Manager? Thank you!

@JRC326 The most important part is to put your TV under the same network. There are multiple ways to do that, for your exact router model, the easiest way is to switch it to "Access Point" mode. Please follow the instructions in your router's booklet.

@mariotaku HI TAKU: I changed my router setting to "ap mode" with asus app, but it didn't work (my wifi signal is gone and the router starting shines a breathing green light). So I reset it and put the router in the study room. here is my setting now:
living room network socket--wire--TV study room network socket--wire--asus zenwifi xd5 router--wire--PC then I try again add device on DEV Manager,and it works fine. I installed moonlight on my TV successfully. But when I launch moonlight on TV, I can't find or add my PC(by type in PC IPV4 address) I know the situation is all about put PC & TV under the same network. Is there any better suggestion for me? THANK YOU!~

If you don't put 2 devices under the same network, one can't access another by default.

    D---G[Other Devices];
    end;
    C---F[Computer];

Please read the booklet thoroughly when you set it up, it should work if you're following the instructions properly.

Closing as this specific problem is solved. If you finish setup and face other issues when you use moonlight, feel free to open an issue there!
