ASP.NET

I am making consumer in Asp.Net using Confluent Kafka. Confluent kafka downloaded from Nuget package. I want to connect with remote server where kafka is deployed using SSL certificate. i am using config for connection

var configSSL = new ConsumerConfig
{
GroupId = groupID,
BootstrapServers = serverUrl,
SslCaLocation = "Config/testcert.p12",
SecurityProtocol = SecurityProtocol.Ssl,
AutoOffsetReset = AutoOffsetReset.Earliest,
Debug = "all",
};
I am not able to connect kafak server using SSL certificate and I am getting error %3|1593785896.458|SSL|rdkafka#consumer-1| [thrd:app]: .\crypto\bio\bss_file.c:175: error:02001003:system library:fopen:No such process: fopen('Config\testcert.p12','r')
