Hi,
According to your post, an error occurred when you accessed the Client.svc file.
We can do as follows:
1.Try to use the following link to access.
http://yoursitename/_vti_bin/Client.svc
2.Try to use Administrator account to login in your server and access it.
3.Check whether the Client.svc file exists in the following folder.
C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\15\isapi
It is recommended to use Client Object Model or REST services in SharePoint 2013.
I suggest you provide your detail requirement for further research.
Best R
