Service callout to a SOAP based webservice getting timed out

[gupta_pratik]

Service callout to a SOAP based webservice getting timed out through APIGEE proxy although getting response when invoking the same service through Soap UI

Things that i have configured

1. Assign message policy

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<AssignMessage async="false" continueOnError="false" enabled="true" name="Assign-Message-LoginRequestForEma">
    <DisplayName>Assign Message-LoginRequestForEma</DisplayName>
    <Properties/>
    <AssignTo createNew="true" transport="http" type="request">loginCelemaRequest</AssignTo>
      <Add>
        <Headers>
            <Header name="SOAPAction">xxxxx</Header>
            <Header name="Content-Type">text/xml</Header>
        </Headers>
        
    </Add>
    <Set>
        <Verb>POST</Verb>
        <Path/>
        <Payload>
            <soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:cai3="http://schemas.ericsson.com/cai3g1.2/">
                <soapenv:Header/>
                <soapenv:Body>
                    <cai3:Login>
                        <cai3:userId>xxx</cai3:userId>
                        <cai3:pwd>xxxxxxxx</cai3:pwd>
                    </cai3:Login>
                </soapenv:Body>
            </soapenv:Envelope>
        </Payload>
    </Set>
    <IgnoreUnresolvedVariables>true</IgnoreUnresolvedVariables>
</AssignMessage>	

2. Service Callout (Note: increased the time out as well but getting the below error)

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<ServiceCallout async="false" continueOnError="false" enabled="true" name="Service-Callout-Celema-Login">
    <DisplayName>Service Callout - Celema Login</DisplayName>
    <Properties/>
    <Request clearPayload="true" variable="loginCelemaRequest">
       <IgnoreUnresolvedVariables>false</IgnoreUnresolvedVariables>
    </Request>
    <Response>loginCelemaResponse</Response>
    <Timeout>300000</Timeout>
    <HTTPTargetConnection>
        <Properties/>
        <URL>http://10.5.129.20:8998</URL>
       
    </HTTPTargetConnection>
</ServiceCallout>


Error:- {"fault": {
   "faultstring": "Execution of ServiceCallout Service-Callout-Celema-Login failed. Reason: timeout occurred in Service-Callout-Celema-Login",
   "detail": {"errorcode": "steps.servicecallout.ExecutionFailed"}
}}
