Browser configuration Not working while recording Gatling scenario

Hi,

I have followed all the steps mentioned in the Gatling documentation to configure my Firefox, Chrome & IE browser to record the load test scenario with Gatling.
I am getting Errors like ‘The proxy server is refusing connections’ & ‘Connection timed out’.
I have cross checked my system settings and open ports according to all suggestions i gathered from the internet.

Any help here?

Gatling is working for http sites, Could anyone please let me know how can i record https sites with Gatling
