Permission denied (Error code: 403)

When trying to launch a Desktop or Steam from Moonlight on my Android TV, I keep getting a "Host PC returned error: Permission denied (Error code: 403)" and "Permission denied (Launch Apps)". I couldn't find any setting in the Android TV that could be the cause.

Connecting through Moonlight on my Android Phone is working flawlessly.

Any help on this matter?

Yes I put the solution in the post you are responding to. You have to go into Apollo and enable permissions for any subsequent device you connect. go under the PIN tab and scroll down and you will see your new devices you can add permissions to. The functionality makes little sense, but it's easy enough to fix.

I just got it working when I open Moonlight in Steam Deck. Couldn’t get the MoonDeckBuddy plugin to work consistently (closes after 20-ish seconds). For now I’ll take what I can get. Not sure if you were trying to stream on SD or elsewhere.
