WCF - Client gets SOAP error on correct webadress, no endpoint listening ?

Hello 

Have a WCF that I can navigate to (browse) and also send in data thru my testprogram to the testserver.  Works all the way. 

But when the client try it on the exe program it gets a soap error that says there is no endpoint listening ???
The first thing I checked is the webadress int the error message but that is correct.  

Does anybody have any ide what this can be ? 
Is it a port issue ? 

Thanks for any help
