Failed to connect to remote target

Hi,

I think I've followed just about every step to install moonlight on my Samsung S90C but still seem to be running into this issue when trying to execute the final step and install moonlight on the TV.

I think I haven't missed any step but stumped here.

Edit- I've also attempted the USB install but it says "app cannot be installed because the validity period has expired."

Make sure dev mode is ENABLED and has your PC ip address on your tv and then restart the tv by pressing the power button for 2 second after doing so.

And then try again with the correct tv ip address in the cmd.

Yup, dev mode is indeed enabled and checked the PC IP address multiple times to ensure it wasn't that.

My only guess after almost 3 hours on this yesterday is it might have to do with ports? My ISP doesn't provide me with access to my router and I can't manually open or check ports myself.

Well this could in fact be the reason, have you tried bridging TV and PC with a phone connection without using the router ?

I made the rookie mistake of getting a PC with no Wifi so need to see if I can borrow a friend's Wifi antenna and try that. Thanks for the suggestion though, if I manage to get my hands on one I'll update on the results! :)

No problem !
Btw some phones allow you to share network with a cable (usb hotspot ?) and WiFi, so you could still try connecting the phone to the PC with a cable and the TV via WiFi

Hello, I'm facing this same problem on a UN43T5300AGXZD TV and before (Aug 27 2024) I was able to. It doesn't seems to be a TV firmware update as it's the same than before (2503), only I upgraded my macOS to Sequoia and installed Mcafee that has a built-in firewall - disabled it but the issue persists. I did a Wireshark capture and running the sdb connect command doesn't seem to send any packet to the TV.
Also, I'm not able to use ping command inside the Docker container, but my PC is able to ping the TV. If the ping and traceroute commands be available inside Docker container it would be nice.
Edit: I figure it out what was going on. mac Sequoia requires to enable "Local network" on Privacy applet to allows Docker to connect to LAN devices:

Same problem on Windows 11. Any tipps?

`docker run -it --rm ghcr.io/oneliberty/moonlight-chrome-tizen:samsung_wasm
moonlight@5dde42360621:~$ sdb connect 192.168.1.193

• Server is not running. Start it now on port 26099 *

I fixed mine by connecting to the TV's assigned IP address instead of the PC host's IP address.

Wasn't able to look back into it until I got back from holiday a couple days back.

The issue was indeed that my ports weren't fully open. Got my ISP to open the ports for one of my connections and connected to that one, worked like a charm. Thanks for the help!
