[grpc-java] InvalidProtocolBufferException: Protocol message contained an invalid tag (zero) error

[Ilya Pavlenko]

Hi guys. We have recently had the same experience. (https://groups.google.com/g/grpc-io/c/q5WP6MYtpNY)The problem occurred only under the heavy load and sometimes it took up to 2 hours to catch it. As you recommended, enabling TLS resolved the problem. 

Could you give any advice for the further investigation? And Y enabling ssl so coordinately resolves the issue? 

PS enabling SSL termination did not help.
