client for online2-tcp-nnet3-decode-faster just hang-up

[QuinnQiu]

Hi , 

I use online2-tcp-nnet3-decode-faster to do online decoding,

however the client just hang-up and get no responses.

I remember that several months ago  it worked fine.  

Don't know why? Want to know how to fix it?

Thank you very much!
