Not able to connect to ADB wirelessly

[wbwxshao]

I followed the steps mentioned here #245 (comment) to try to use WebADB over WiFi. I have the WebSocket.js installed and used the command
node .\websockify.js 15555 localhost:38757
to start. And in the WebADB end (https://tango-adb.github.io/old-demo/) as stated I waited for about 2 mins but the web address didn't show up. So I manually clicked the add button and selected "WebSocket" and then give the address as ws://localhost:15555. But then almost immediately I got the prompt from the brower with the error:

Error: Connection closed unexpectedly
    at https://tango-adb.github.io/old-demo/_next/static/chunks/pages/_app-b8a1688d9ffda068.js:10:9808

And in Terminal I got the error:

PS C:\Users\wbwxs\Documents\webadb\websockify-js\websockify> node .\websockify.js 15555 localhost:38757
WebSocket settings:
    - proxying from :15555 to localhost:38757
    - Running in unencrypted HTTP (ws://) mode
/
 ::1: WebSocket connection
 ::1: Version undefined, subprotocol:
 ::1: target connection error
 ::1: WebSocket client disconnected: 1005 []
/

So any idea why this will happen?

Thanks in advance!!

 ::1: target connection error

Your WebSockify program can't connect to localhost:38757. Make sure the address is correct (usually it's your phone's IP and wireless debugging port).

Yeah I checked that, it's matching the address and port listed in the "Wireless Debugging" section on my phone. Is there anything else that could cause this error?

[yume-chan]

Your device shows localhost in wireless debugging page? Can you show me a screenshot?

The issue exists between WebSockify and your device. Can your PC connect to your phone, for example using ping?

[wbwxshao]

Not localhost, but it will show the ip address and port to use the wireless connection.

Yes I can use adb connect to connect to the phone but somehow WebSockify is not working

Update:
I made a mistake when using WebSocket, I should use something like: node .\websockify.js 15555 192.168.2.240:38995 instead of using localhost:port number. Now there is something changed with websockify end saying "connected to target", but didn't see any authorizaiton prompt on the device

@yume-chan Could you please check and advise here? Thanks!

Android 11 wireless debugging doesn't use the old authorization prompt. The client must be already authenticated on USB connection, or using adb pair to get authorized (Tango doesn't support the protocol of adb pair). So if you have connected to that device in Tango over USB, it should also work when connected wirelessly (I haven't tested this).
