Question

Hi all,

We are trying to access the Appian web service (process model exposed as a web service) from outside the Appian environment.

The endpoint for the web service is: bpm-meridian-uat.alldata.net/.../PRFMeridianProcess. Though, we are able to access the web service endpoint directly in a web browser. But when we try loading web service in SOAP UI, it gives the following error.

Error loading [https://bpm-meridian-uat.alldata.net/suite/webservice/processmodel/PRFMeridianProcess?WSDL]: java.lang.Exception: Failed to load url; bpm-meridian-uat.alldata.net/.../PRFMeridianProcess, 0

To load the WSDL in SOAP UI, we downloaded the WSDL and browsed it from our local machine. Now making a call to web service results in failure, please find below the error message.

ERROR:javax.net.ssl.SSLHandshakeException: Remote host closed connection during handshake

However on the same env...

From the error, looks like a web server config issue. 
 
BTW, your web server has issues with the SSL configuration. 
 
See this report from SSL Labs on your site..

Two recommendations.. 
 
First) . Choose Appian Cloud instead to ensure you have a highly secure and properly configured web server. This will also save you time from worrying about maintaining the server, which is done for you by Appian Cloud team. 
 
Second) . After you get your web server issues squared away, suggest changing to using Appian Web API designer to publish your processes. This uses the latest REST standards instead of SOAP and provides more flexibility in how you choose to expose your process endpoints.
