For some reason, I need to test a website in some specific browsers on smartphone.  
So I tried to run test in Remote execution with local Appium server, but it show some error that I can’t deal with.  
Here are my steps:

1. Connect my smartphone using adb, boot up Appium;
2. Run Remote execution in Katalon;
3. It shows that the browser is start up (com.vivo.browser), but some errors has thrown in katalon (at org.codehaus.groovy.tools.GroovyStarter.main(GroovyStarter.java:131));
4. The test case continue and open the url correctly, but error thrown in katalon (com.kms.katalon.core.exception.StepFailedException: Unable to open browser with url), and many same errors thrown in Appium(Error: Could not proxy. Proxy error: Could not proxy command to remote server. Original error: 404);

As the appActivity and appPackage in properties, it can be changed to com.google.android.apps.chrome.Main and com.android.chrome and the error shows as before.

Here are logs and my costume execution config below.
