I have a WCF service that worked fine until a "service-window" had elapsed and now I can figure out what is wrong. I can from machine A, browse to the service http://xx.xx.xx.xxx/Service/Service.svc and http://xx.xx.xx.xxx/Service/Service.svc?wsdl it work fine. BUT when I'm trying to use the service it don't. To eliminate everything, I have been testing with the WCF Test Client provided by Visual Studio.
When I trying to add the service connection to the Testing tool I get a "Service located at x is too busy" and "(503) Server Unavailable" error. But if I use the same test client directly on the WCF Server everything works.
The service haven't been updated or change since it worked so there isn't anything wrong with the code.
There is some nasty firewalls or something like that between these machines but since the svc file is accessible I get confused.
I don't know where to look for more clues, need help.
