GRPC + TLS Exporter not working

[kadhamecha-conga]

        hi
        
        i'm facing issue while exporting traces from nginx with open telemetry enable , and send it over grpc and TLS enable in NLB
        
        GRPC Exporter is failing to establish a connection with the configured endpoint, resulting in the inability to export trace data.
        
        [Error] File: /tmp/build/opentelemetry-cpp/exporters/otlp/src/otlp_grpc_exporter.cc:66 [OTLP TRACE GRPC Exporter] Export() failed with status_code: "UNAVAILABLE" error_message: "failed to connect to all addresses; last error: UNKNOWN: ipv4:x.x.x.x:443: connection attempt timed out before receiving SETTINGS frame"
        
        otlp-collector-host: test.example.com (Redacted)
        otlp-collector-port: 443

        helm.sh/chart : ingress-nginx-4.11.3
        app.kubernetes.io/version : 1.11.2
        
        thanks,
