XIServer error raised: 503 Service Unavailable with SOAP Adapter

Question

Hi,
We are getting a very strange error from a process that is working fine in 2 other environments.
We are sending a message into the SOAP receiver adapter and are getting the following error at the Call Adapter part of the process :
<?xml version="1.0" encoding="UTF-8" standalone="yes" ?>
- <!--  Call Adapter
  -->
- <SAP:Error xmlns:SAP="http://sap.com/xi/XI/Message/30" xmlns:SOAP="http://schemas.xmlsoap.org/soap/envelope/" SOAP:mustUnderstand="1">
  <SAP:Category>XIServer</SAP:Category>

  <SAP:P1>503</SAP:P1>

We are on XI 3.0 SP13.
Any suggestions ?
Kind regards

Hi Colin,
Quick look into these-
1) Are you able to test the WebService, because the error tells about unavailable...

2) Is your SOAP Receiver COnfiguration is correct

3) Check the  wsdl is correct and try look into the input message for the Webservice(SOAP Adapter)
Have a look into this thread-
503 service unavailable
Hope this helps,
