Using HTTP_CLIENT-->receive, NIECONN_REFUSED error

[Amey-Mogare]

Hi,

I am facing Http_Communication_Failure in using IF_HTTP_CLIENT->receive method.

SICM logs gives following error:-

NIECONN_REFUSED

Also when I tested same url with FM HTTP_GET, it gives Connect error as "NiHostToAddr <hostname> error: NIEHOST_UNKNOWN

I really surprised to see that this was working fine few weeks back.

Now suddenly it has stopped working.

Please help.

Thanks and regards,

Amey

Hello,

Could you please let me know how you solved this issue?

Hi Sudheer,

I could resolve the issue by the exact code I typed in my reply above.

I was not setting some HTTP attributes previously (content-type n etc).

Once I set those in http-client's object, it started working.

Try using same code that I put up.

Hope it helps.

Thanks,

Amey
