Randomly stuck in API when there is network issue

[brt-tiep-duong]

Hello,

We face an issue when we call the API LoadPropertiesForItems. Sometimes, when there is network issue, the API never returns, no error message either.
We suspect that it was the TCP keep alive which cause the issue. The connection has been lost but unable to be detected.

Does anyone face this issue? Any suggestion? We're using version 0.9.3

Thanks
