Wiremock using certificate not working on Windows

This error only happens on the Windows OS. On Linux and MacOS it works fine.

I've made sure that the password for the certificates is correct, that they do exist in the mentioned location and that the port is available. Language is Kotlin. Testing framework is Kotest.

Certificates are under: test/resources/ssl-certs/client-cert.p12 test/resources/ssl-certs/server-cert.p12

            val response = request.execute()

            response.statusCode shouldBe HttpStatus.OK

            apigeeMockServer.verify(

The error I'm getting (only on Windows):
