Hi @learngatling2022,

JVM does not take certificate and key directly. You’ll have to create a keystore.  
Plenty of articles on the internet are already present to explain you that.

Try creating a `JKS` or a `p12` from your certificate and key and configure that in your `gatling.conf` file.

Cheers!
