Starting Appium Programmatically - Connection Refused (Connection Refused)

Description

@SrinivasanTarget @mykola-mokhnach @TikhomirovSergey @jlipps

I am trying to start Appium programatically and pass its IP and Port into AppiumDriver

Before I pass it to the driver, I sys.out.println the Appium Service’s IP/Port it is running on to the console, and it is 0.0.0.0:4723.

Yet, I am getting a Connection Refused after passing it to driver (See stack trace). If I manually start Appium, it is starting on 0.0.0.0:4723, just fine.

Please find my code and StackTrace below. I really need help. Many thanks.

Environment

• java client build version or git revision if you use some shapshot:
• Appium server version or git revision if you use some shapshot: 5.0.1 Java-client
• Desktop OS/version used to run Appium if necessary: Ubuntu16
• Node.js version (unless using Appium.app|exe) or Appium CLI or Appium.app|exe:
• Mobile platform/version under test: Nexus5 Kitkat
• Real device or emulator/simulator:

Details

Please provide more details, if necessary.
