Unexpected Error: Couldn't load the model schema

Upon trying to connect to an SQL Server database using DirectQuery, I encountered an Unexpected Error: Couldn't load the model schema. I had read some of the solutions such as removing the :port number when entering the server name but it doesn't work for me.

 

I have attached the log below and would appreciate help on how to resolve the error. Many thanks in advance.

Re: Unexpected Error: Couldn't load the model schema

Hi Frank, 

 

The error has been resolved when the port number is entered after a comma behind the server name.

servername, portnumber instead of servername: portnumber

Re: Unexpected Error: Couldn't load the model schema

I am getting the same error when connecting to Oracle (v12) via Gateway. I have already tried deleting the connection cache under Global Permissions outlined in another post. 

 

Cannot load model
Couldn't load the model schema associated with this report. Make sure you have a connection to the server, and try again.
Please try again later or contact support. If you contact support, please provide these details.

 

Where would you make this change of comma/port, behind the server name?
