Any idea why it failed?

Couldn't execute warm up request http://gatling.io

Ping to it is okay but telenet to it failed.

Works fine for me. Maybe that's being blocked by your organisation?

$ ping gatling.io

See the documentation around auto warm-up - you can either change the URL (to something accessible) or just disable it, assuming it's a connectivity issue from your injector to the internet?
