There was no endpoint listening at (url) that could accept the message
Another case I just had - when the request size is bigger than the request size set in IIS as a limit, then you can get that error too.
Check the IIS request limit and increase it if it's lower than you need.Here is how you can check and change the IIS request limit:
- Open the IIS
- Click your site and/or your mapped application
- Click on Feature view and click Request Filtering
- Click - Edit Feature Settings.
I just found also another thread in stackIIS 7.5 hosted WCF service throws EndpointNotFoundException with 404 only for large requests
