need networking / dlang experts to help with a grpc issue

[mw]

Hi,

We have trouble to use D grpc client to talk to Python grpc 
server, and vice versa:

https://github.com/huntlabs/grpc-dlang/issues/15
https://github.com/huntlabs/grpc-dlang/issues/17

right now, D grpc client can only talk to D server.


This issue has been logged for a while, and the package 
maintainers have tried, but unable to fix it.

Just wondering if any networking / dlang experts on this forum 
can take a look, and help fix this grpc issue. (it could be some 
simple communication mismatch in an expert's eyes, hopefully).


Thanks.
