originChannel is not active

getting following error on subcription
{"subscribe_stream_error":{"msg":"originChannel is not active","channel_state":"IDLE","function":"SubscriberClient.createRequiredStream.context.run"},"runtime_id":"9ef01e92-0bc3-4756-b847-a8b1e6ebaf4f"}

Generally when there is no activity on the channel GRPC would move the current state of the channel to IDLE. If you are running a non TLS connection, set the env property TLS_PEM_FILE=none.
