Hello everyone,

I am facing an issue while trying to run/install my webOS TV app on the emulator using **webOS Studio**.

When I try to install the IPK, I get the following error:

> **ERROR: Failed to install**  
> `.ipk on emulator`  
> `ares-install ERR!`  
> `Syscall failure: connect ECONNREFUSED 127.0.0.1:6622`  
> `Please check the device IP address or the port number`

**Environment details:**

- OS: Windows

- IDE: webOS Studio

- Emulator: LG webOS TV Emulator (offline/default)

- App type: webOS TV web app

- Emulator IP: 127.0.0.1

- Port: 6622

**What I’ve checked so far:**

- Emulator is added under **Known Devices**

- Device status shows **offline/default**

- App builds successfully, but installation fails

- webOS TV Simulator shows “not installed” in Simulator Manager

I’m not sure if this is related to the emulator not running properly, port issues, or a missing simulator package.

Could anyone please guide me on:

- How to fix this connection refused error?

- Whether I need to

- Any required settings for emulator/device connection?

Thanks in advance for your help 🙏

Please check if you have installed emulators first. You can find the list of installed emulators in the [EMULATOR MANAGER](https://webostv.developer.lge.com/develop/tools/webos-studio-dev-guide#emulator-manager) view. Thank you.

Do you mean you have installed emulators? Or is the problem with testing apps on a TV device, not the emulator?
