Getting "OPENSSL_internal:UNSUPPORTED_PROTOCOL" in recorder

Gatling (Open-Source)
1

I’m trying to use Gatling Recorder on my mac. So I’ve set the proxy mode and generated cert file by using Certificate Authority mode. Then I’ve send cert file to my iPhone by email and installed it in iOS. Also I’ve setup proxy on my iOS.
When I Start recorder I can see only http requests, but can’t see any https requests. Also I see a lot of errors in the console like this:

Where is the issue? I can see installed Gatling profile in my iOS as well…

Hello @Artem,

It looks like you tried to connect with https when there is no SSL server-side.
Can you try with removing the “s”?

Cheers!
