When users access the Web Client, the following error may be logged to the Diagnostics Console:
-
Cannot create channel sink to connect to URL ''. An appropriate channel has probably not been registered.
On the login page, the following error is displayed:
-
The server encountered an error when connecting to the database. If this problem persists, you should contact your administrator for resolution.
These errors occur when the URL to the Application Server is blank or incorrect in the AppNet (Web Server) Web.config file. The correct value will depend on the communication method used: Remoting or SOAP.
Remoting allows the Web Server to use binary over HTTP to communicate with the Application Server. If the ServiceClientType attribute in Web.config is set to Remoting, then the ApplicationServer URL should be set to http://ServerName/AppServer/service.rem.
SOAP allows the Web Server to use XML SOAP over HTTP to communicate with the Application Server. If the ServiceClientType attribute in Web.config is set to SOAP, then the ApplicationServer URL should be set to http://ServerName/AppServer/service.asmx.
