migration help from 2.1.7 to 2.2.5

hello people!

I m trying to update my gatling from 2.1.7 to 2.2.5 (latest stable version)

i have followed the guide for migration of gatling from 2.1.x to 2.2.x on the website but right now when i run my dry run test on scenarios i faced failures on warmup even when i changed my timeout settings in gatling.conf and i have failed requests on my tests scenarios too when i dont face any issues on 2.1.7.

15:49:49.974 [INFO ] i.g.h.a.HttpEngine - Start warm up
15:49:51.016 [INFO ] i.g.h.a.HttpEngine - Couldn’t execute warm up request http://www.test.com
java.util.concurrent.TimeoutException: Request timeout to www.test.com after 1000 ms
