HTTP client code 400 reason ICM_HTTP_CONNECTION_FAILED

[Former Member]

Hello,

We have a scenario RFC --> XI --> HTTPS.

We get 1500 messages per day. However 8-10 of them fails giving following error.

<SAP:Error xmlns:SAP="http://sap.com/xi/XI/Message/30" xmlns:SOAP="http://schemas.xmlsoap.org/soap/envelope/" SOAP:mustUnderstand="1">

<SAP:Category>XIAdapter</SAP:Category>

<SAP:Code area="PLAINHTTP_ADAPTER">ATTRIBUTE_CLIENT</SAP:Code>

<SAP:P1>400</SAP:P1>

<SAP:P2>ICM_HTTP_CONNECTION_FAILED</SAP:P2>

<SAP:P3 />

<SAP:P4 />

<SAP:AdditionalText />

<SAP:ApplicationFaultMessage namespace="" />

<SAP:Stack>HTTP client code 400 reason ICM_HTTP_CONNECTION_FAILED</SAP:Stack>

<SAP:Retry>N</SAP:Retry>

</SAP:Error>

What could be the reason? Please help to resolve this.

Thanks in advance,

Beena.

SAP Library - Components of SAP Communication Technology

Measurement Protocol Developer Guide - Google Analytics &amp;mdash; Google Developers

I hope, you can solve this.

I checked ICM trace and it shows below error. But I don't know the reason for connection failure.

Hi Beena,

Check the third-party server is up and running.......i think your HTTPS server is down, so your connection from XI to your third-party server is not running and you are seeing the above error in your ICM trace.
