Mongo go driver - giving key mismatch error while connecting with ssl enabled and encrypted key

Working with Data Drivers
1

I’m getting following error while trying to connect to mongodb server from golang application kubernetes pod.

tls: private key does not match public key

I’m using mongo-go-driver version 1.4.1

Key is RSA encrypted. -----BEGIN RSA PRIVATE KEY----- Proc-Type: 4,ENCRYPTED DEK-Info: …

PFB application code to connect

    m.context, _ = context.WithTimeout(context.Background(), 30*time.Second)

    certFilePath := <path>
    keyPassword := <password>

    uri := "mongodb://user:password@<mongoserver>:27017/?authSource=<dbname>&authMechanism=scram-sha-1&connect=direct&ssl=true&sslClientCertificateKeyFile=%s&sslClientCertificateKeyPassword=%s&sslInsecure=true&sslAllowInvalidCertificates=true"
    uri = fmt.Sprintf(uri, certFilePath, keyPassword)

    log.Println("ConnectDB: creating mongo client new")
    clientOptions := []*options.ClientOptions{
        options.Client().ApplyURI(uri),//.SetAuth(credential),
    }

    log.Println("ConnectDB: connecting client")
    m.client, err = mongo.Connect(m.context, clientOptions...)
    if nil != err {
        panic(err)
    }

Same key and certs are working fine when connecting using Robo 3T or Studio 3T

Please help me in resolving key mismatch error.
