Answer 1

The issue was proxy internet. The Captcha was unable to connect to google server due to proxy. As reCaptcha v2 has https link, therefore by adding following code in setDomainEnv.cmd captcha is now working fine.

set JAVA_OPTIONS=%JAVA_OPTIONS% -Dhttps.proxyHost=172.18.101.2 -Dhttps.proxyPort=80 -Dhttps.nonProxyHosts="127.*|localhost"
