Error 0A080009 using SSL

[csolamx]

Hello,

I am using librdkafka through confluent-kafka-dotnet. I am trying to implement secure communication through a client certificate, so I am setting the following configuration:

"SslProviders": "default",
"SslCertificateLocation": "cert.pem",
"SslKeyLocation": "cert.pem",
"SslKeyPassword": "************"

This works locally, however when I use the same in the server, I get the following error:

error message = ssl.key.location failed: error:0A080009:SSL routines::PEM lib, Trace = at Confluent.Kafka.Impl.SafeKafkaHandle.Create(RdKafkaType type, IntPtr config, IClient owner)

I have looked for this error code, however I can't find specific causes or solutions.

Any help will be greatly appreciated.

Regards
