Hello,
I am working on IIB 10.0.0.1
I am invoking an external web service using HTTPS.
All the certificates are in place.
When I directly invoke the external web service using SOAPUI, it returns me a result but when I invoke it from IIB, it returns service unavailable 503.
Any ideas of any configurations I am missing? |

You need to take a user trace. This will tell you what the error may be in more details. Have fun

This is what I get from user trace too.
The broker has received data via HTTP from a remote server at host 'xxxx' with an HTTP status code of 503. |

Check the error logs of the remote service to see why it's returning 503 ?

HTTP 503 is temporary state.
If you are able to hit it from SOAP UI but not from IIB then
1. you need to check the connectivity betweeen IIB and target server.
2. Make sure, the URL that IIB uses to hit backend is exactly the same.
3. Check the HTTP headers that are being sent from IIB.
If that does not give you any pointers - then you may want to do packet capture between IIB and backend system. |

Hi VishBroker,
How do I check connectivity between IIB and backend server?
And how do I check packet capture between the two systems? |

The system that has broker - should be able to ping the target server.
This tells you the connectivity between IIB and backend server.
For packet capture - there are few network sniffing tools. Your network team should be able to capture it.
Have you tried to look at the HTTP headers that are being sent?
By the way -
As you are getting 503 - it seems that you are able to hit the backend
YOu need to check at the backend - what error you are getting.

The server is currently unable to handle the request due to a temporary overloading or maintenance of the server. The implication is that this is a temporary condition which will be alleviated after some delay. If known, the length of the delay MAY be indicated in a Retry-After header. If no Retry-After is given, the client SHOULD handle the response as it would for a 500 response.
Note: The existence of the 503 status code does not imply that a
server must use it when becoming overloaded. Some servers may wish
to simply refuse the connection.
