I have a outbound endpoint that is no longer working. It worked for awhile then stopped today. I get "org.apache.commons.httpclient.NoHttpResponseException: The server bill-centos6.billmax.com failed to respond" delivery failure messages. However i see no network traffic on the port the endpoint responds to. I can reach the port just fine from a web browser so it is not a nework or firewall issue.

The endpoint is a gsoap built service responding on port 1800. What is wrong here? How do the heck do I find out what salesforce is attempting? Are there logs somewhere?
 

Hi All, 

 Could i please get some assistance in figuring out where the issue is.  what can be possible issues in my sand box when it's outbound message are getting errors while talking to client's web server. 

endurl: https://cramappstage.edgewebhosting.net/EdgeSalesForce/EdgeSalesforce.asmx
error: org.apache.commons.httpclient.NoHttpResponseException: The server cramappstage.edgewebhosting.net failed to respond

I have no clue where to look or if the issue is on my end. Any feedback is appreciated.
