I tested it myself and don't find any problem. Can you provide OS version, python interpreter (CPython or pypy or micropython), python version of the server and version of Windows on your client computer?

[MoeGakuen]

Windows OS version: 10.0.17134.441(1803) Python version for Linux(Centos7): 2.7.5

There is no problem using 87384a0e649a41b8e7ac031d5ab1a1729aa0dc77 or older versions.

[ThunderEX]

I can reproduce your issue now. I'll try fix the issue. Thanks for feedback!

[ThunderEX]

Hi @MoeGakuen I commit 758e616d6f9cd5dea6a14d6e4ad2c02e9402ecaf and I've tested myself. Could you please check if it resolve your problem?

[MoeGakuen]

Thank, It is now running normally without any problems.
