Rescue in block in connect error

[Julian Nesteriuc]

Hi all,

I'm new to Selenium and I've recently installed it on my PC but I'm having this issue:

C:\Ruby24-x64\bin\ruby.exe -e $stdout.sync=true;$stderr.sync=true;load($0=ARGV.shift) C:/seleniumframework/watir_cucumber_template-master/features/step_definitions/test_file.rb

Can someone help me please?

Thank you,
