Cannot create connection using "IP\host,port" format.
Cannot create connection using "IP\host,port" format in Spotlight.
This format is not supported by Spotlight usage of JDBC driver.
In case of using a named instance, there is no need for a port number. If in case of specifying the port, then there is no need to specify the instance name. Only one of these values is needed. If using a cluster and named instance is required, ensure the port required is opened so it is not required in this field.
