java.security.cert.CertificateException: No name matching localhost found

[Hemanshu Patira]

Hi All,

I am trying to execute gatling on my tomcat running on my local-VM. The VM uses SSL cert. I have already added the cert in gatling.conf under keystore section. I am getting the below error:

The same cert is present on our DEV environment and it works fine. Its not able to connect localhost and I am able to connect my local host through all other means, like JMeter, SOUPUI, POSTMAN, facing this issue only with gatling.

Can anybody give some pointers on fixing this issue ?

Thanks,
