Appium 1.7.1 Encountered internal error running command: Error: Could not proxy. Proxy error: Could not proxy command to remote server. Original error: Error: socket hang up

The problem

I am running test scripts using appium 1.7.1 with uiautomator2 for testing android apps. While running i am getting Error Encountered internal error running command: Error: Could not proxy. Proxy error: Could not proxy command to remote server. Original error: Error: socket hang up at doJwpProxy$ (../../../lib/mjsonwp/mjsonwp.js:384:13) at tryCatch (/usr/lib/node_modules/appium/node_modules/babel-runtime/regenerator/runtime.js:67:40) at GeneratorFunctionPrototype.invoke [as _invoke] (/usr/lib/node_modules/appium/node_modules/babel-runtime/regenerator/runtime.js:315:22) at GeneratorFunctionPrototype.prototype.(anonymous function) [as throw] (/usr/lib/node_modules/appium/node_modules/babel-runtime/regenerator/runtime.js:100:21) at GeneratorFunctionPrototype.invoke (/usr/lib/node_modules/appium/node_modules/babel-runtime/regenerator/runtime.js:136:37)

I am using appium-python-robotframework for writing test scripts. The above error occurs when I am using uiautomator2 for testing Android phones with v7 and above. The automation runs fine when I am using automationName=appium for testing Android phones below v7.

Some times I am getting the ECONNRESET error in between the test cases: WebDriverException: Message: An unknown server-side error occurred while processing the command. Original error: Could not proxy command to remote server. Original error: Error: read ECONNRESET

I am getting these two errors switching in between as random. Some of the test cases passes without fail. But some fails with these errors.
