Any idea why I'm getting this error?

i.g.h.a.HttpEngine - Couldn't execute warm up request http://gatling.io
java.util.concurrent.TimeoutException: Request timeout to gatling.io/192.30.252.153:80 after 1000ms

Do you have active internet connection? :-)

Yes, my Micro Service tests are working fine. I have a no issue as such which can block me here but I just wondered why I'm getting this exception.

Same here. Why does Gatling call home to warm up the cache? And why does it fail? (yes, I do have a working internet connection)

Sometimes, depending on your host and network, this request can time out. And the timeout is pretty low to not hurt start up time, all the more if you're actually being a proxy and Gatling can't reach the internet.
Then, this is a DEBUG log.

In the end, it all boils down to reading the doc...
