[WDS] Disconnected! net::ERR_CONNECTION_REFUSED

# Bug report

**What is the current behavior?**
Hi, it took a few months to debug the adb in android gives me problems. I connect the device, accept the debugging authorization and every 20 minutes it disconnects alone, thus popping up again to accept authorization. I debug the apps with livereload, I use the ionic 4 framework. Does anyone know why that happens? Some time ago this was working correctly but I don't know if it's an adb problem or not.

**If the current behavior is a bug, please provide the steps to reproduce.**

I use the Ionic Framework with version 4, but this happens to me with any version,
**1.** I connect my device to the PC.

**2.** I accept the authorization of debugging.

**3.** I check with the adb devices command that my device recognizes.

**4.** You recognize it.

**5.** I launch my application with the command:
`ionic cordova run android --livereload --consolelogs.`

**6.** I open the chrome bug to debug my app and see the logs.

**7.** When 20 minutes have passed, the authorization popup reappears on the device and I get the following error in the DevTools console

Error por consola:
```
[WDS] Disconnected!
close @ vendor.js:137905
```

```
Failed to load resource: net::ERR_CONNECTION_REFUSED

```

**What is the expected behavior?**

Just months ago or last year this didn't happen. I did not give this error every 20 minutes.
