Why do I sometimes report this error? There is no problem with the frida connection.

[IPMegladon]

Can you please run objection with -d and provide the debug output? Does it work fine when using the PID or process name?

[watermelon520]

Like I said, it happens occasionally. It can be connected now, but the error was reported directly.

frida.TransportError: timeout was reached

[IPMegladon]

Keep in mind the syntax you are using tries to attach to an already running app instead of spawning it. That last error usually occurs when the device is locked or the app is not on the foreground.
If you getting the issue again, try to restart the app, or use objection -s -p -n com.funplus.ts start to have objection/frida (re)start the app and see if that maybe fixes it.

It happened again

[watermelon520]

I tried restarting the app and it didn't work. objection -s -p -n doesn't work either
