Unable to run the selenium script while connected to the LAN - selenium

Question

Unable to run the selenium script while connected to the LAN, however it works fine when connected to the WIFI. I have kept all the proxy settings same.
Below is the code:
String exePath = "/usr/local/bin/chromedriver";
System.setProperty("webdriver.chrome.driver", exePath);
WebDriver driver = new ChromeDriver();
driver.get("https://www.google.com");
OS: Mac 10.11.6
Selenium: 2.53
Also tried with 3.8.1
ChromeDriver: 2.33.2
Chrome: V60.
Eclipse Oxygen.
Getting Below mentioned error message:
Starting ChromeDriver 2.33.506106 (8a06c39c4582fbfbab6966dbb1c38a9173bfb1a2) on port 21777

The error says it all :
Exception in thread "main" org.openqa.selenium.SessionNotCreatedException: session not created exception
from disconnected: unable to connect to renderer
(Session info: chrome=60.0.3112.113)
(Driver info: chromedriver=2.33.506106 (8a06c39c4582fbfbab6966dbb1c38a9173bfb1a2),platform=Mac OS X 10.11.6 x86_64) (WARNING: The server did not provide any stacktrace information)
Command duration or timeout: 2.65 seconds

The main reason is the binaries you are using are incompatible as :
You are using ChromeDriver v2.33 of (2017-10-03)
Your Chrome Browser version is 60.x
Your Selenium Client version is 2.53.1 of time: '2016-06-30 17:32:46'
So there is a time gap of almost 2 years between the release of Selenium Client v2.53.1 and ChromeDriver v2.33
Solution
Upgrade your Selenium Client to recent Selenium v3.9.1 level.
Upgrade your ChromeDriver to recent ChromeDriver=2.35 level.
As per the Release Notes of ChromeDriver=2.35 upgrade your Chrome Browser to Chrome v62-64 levels.
If your base Chrome Browser version is too old uninstall Chrome Browser through Revo Uninstaller and install a recent released GA version of Chrome Browser
Run CCleaner tool regularly to wipe off all the OS chores before and after the execution of your Test Suite
Execute your Tests
Update
As you mentioned you are unable to run the script while connected to the LAN but works fine when connected to the WIFI you need to ensure the following :
Ports used by the WebDriver variants (GeckoDriver / ChromeDriver / IEDriverServer) are not used by any other Software/Services over the LAN.
Ports (range of ports) are not blocked by the LAN Admins for specific purpose.
Firewall is disabled.
