WSL2 - Unable to apply changes on device ECONNREFUSED livesync

[mrkvn]

Environment

• CLI: 7.0.12
• Windows Subsystem for Linux (WSL2)

Details

After running tns run android, the app compiles properly but not hot reloading. Got an error:
Unable to apply changes on device: emulator-5554. Error is: connect ECONNREFUSED 127.0.0.1:40547

After using --log trace, found that port 40547 (changes every run), in this particular run, is related to livesync, maybe.

spawn: /home/user/android/platform-tools/adb "-s" "emulator-5554" "forward" "tcp:40547" "localabstract:org.nativescript.application-livesync"

tns run android

Expected behavior

Hot Reload.

Additional context

Trying to setup nativescript-vue in windows wsl2. Made it to work. It compiles correctly. For reference, I used the following write-ups/articles to set it up.

1. rearct-native-app-in-wsl2
2. Using the Android emulator on Windows 10 with WSL2

I only used the basic app template from vue init nativescript-vue/vue-cli-template.

tns doctor

I've already searched google looking for answers. I found same error asked in stackoverflow but there are no answers and their question has no details/context behind it, so I'm not sure if they really have the same issue as this.

Not sure if this is a WSL2 specific problem with ports. If it is, I hope someone could point me in the right direction on how to solve this. Thanks

Since this issue is still open even if a solution has been deployed, to anyone coming by:

Summary of the feature: what you have to do is to set the NATIVESCRIPT_LIVESYNC_ADDRESS env variable to whatever IP you used for the ADB Server socket (your WSL ADB connecting to the Windows one.).

// or put it in alongside your ADB_SERVER_SOCKET in any .bashrc / .zshrc file
NATIVESCRIPT_LIVESYNC_ADDRESS=172.16.0.1 tns run android
