I run Gatling recorder for site with selfsigned certificate. As I understood, I must accept also Gatling certificate for this site, but I didn’t get any message or alert about Gatling certificate, so I can’t accept it… When I try to login on my tested site (with proxy and Gatling recorder turned on) i can’t even go further than login\_page…

When I run recorder, I get following:  
GATLING\_HOME is set to “C:\Workspace\Stress\_Test\_Gatling”
