Secured Read Failed - FD Shutdown error on Async GRPC request #427

I'm having issues with the async grpc reqest. I have uploaded the audio raw file to GS under the project with the service account I'm using for authentication.

I'm able to access the file fine via gsutil and verified that the ACL seems to have the service account:

johndoe@xyz.com:~/google/python-docs-samples/speech/api$ gsutil cp gs://#####/audio.raw .
Copying gs://#####/audio.raw...
Downloading file://./audio.raw: 56.6 KiB/56.6 KiB

johndoe@xyz.com:~/google/python-docs-samples/speech/api$ gsutil acl get gs://#####/audio.raw
[
{
"email": "#####@call-qa.iam.gserviceaccount.com",
"entity": "user-#####@call-qa.iam.gserviceaccount.com",
"role": "OWNER"
}
]

But, keep getting the following transport errors

johndoe@xyz.com:~/google/python-docs-samples/speech/api$ python speech_async_grpc.py gs://#####/audio.raw

Which looks like it just can't reach Google Storage to read the file? Just not sure what else to do or how to verify I have things setup properly. I'm hoping this is just a permission issue and I'm being stupid :)
