WebSocket connection failed

[csdaa]

What is the issue or idea you have?

After restarting the server every week and reconnecting the phones, there are always 2 to 3 phones that cannot be controlled, with the message 'WebSocket connection failed' seen from the Chrome dev tools.

Does it only happen on a specific device? Please run adb devices -l and paste the corresponding row.
I connected 15 mobile phones....It is not a specific device, but rather randomness.

adb devices -l
List of devices attached
R5CW30TQ57K            device product:a54xzc model:SM_A5460 device:a54x transport_id:3

Please provide the steps to reproduce the issue.

1. Execute the command 'adb nodaemon server -a -P 5037' on the client.
2. Execute the command: 'stf provider --name "R" --min-port 7800 --max-port 7810 --connect-sub tcp://127.0.0.1:7114 --connect-push tcp://127.0.0.1:7116 --group-timeout 900 --public-ip 192.168.58.200 --storage-url http://localhost:7100/ --adb-host 192.168.145.171 --adb-port 5037 --vnc-initial-size 600*800 --mute-master never --allow-remote' on the server.
3. Click the device control button in the browser.

What is the expected behavior?
The device can output images.

Do you see errors or warnings in the stf local output? If so, please paste them or the full log here.

It means another process on your machine listen on port 7400, probably a STF process which has not been cleanly stopped!

Thank you very much. I also noticed the abnormal port occupation, but what caused it? Could it be the command from step 2 of the problem reproduction?

[denis99999]

@csdaa , it seems also you are launched a stf local server on the same machine, isn't it ?

[csdaa]

@csdaa , it seems also you are launched a stf local server on the same machine, isn't it ?

Yes, that's right.

I am currently learning "DeviceFarmer-stf" and am using three computers for testing: a server, node 1, and node 2. Node 1 and node 2 are used to connect to mobile phones, and then on the server side, I execute the command "stf provider --name 'R' --min-port 7800 --max-port 7810...." to connect the mobile phones from node 1 and node 2 to stf.
This is the method I found online.I know there is another more complex way that requires configuring "storage" and so on, but it demands too much time investment, and I don't have time, so I'm using the current method.

Could you please tell me about the usage documentation for stf?

I hope to give back to everyone the knowledge I've learned in the 'issue'.
