Trouble previewing a Dashboard

When I click on the "Preview" button in the Dashboard Designer, the widgets come up blank, and the page eventually shows an error at the top of the screen "Dashboard could not be viewed due to an error. Learn More".

The error presented shows the following:
---------------------------------

---------------------------------

In addition, the web browser's network log shows that the DashboardService.svc/InitializeControls URL returns a 500 error.   Attempting to access that service directly returns the following:

Method not allowed. Please see the service help page for constructing valid requests to the service.

Please me know if there is a way to fix this.  Thank you.

Hi Duran,   
Please let us know whether you are using web API as Data Source or not. If yes, this issue was fixed in the refresh build which was updated on Jan 19, 2017. Please download the refresh build from the link:  
If not, please provide additional information such as data source you have used and your system time zone.  
Regards,

DU Duran March 3, 2017 05:14 PM UTC

I am not using a web API data source, all data sources in use are Microsoft SQL Server.
I am currently using version 2.1.0.2
My system's time zone is currently reported as "(UTC-06:00) Central Time (US & Canada)"

Let me know if you need further information.

Hi Duran,   
   
We were unable to reproduce the issue. Please provide the error log file generated in the below location   
%appdata%\Syncfusion\DashboardDesigner\< DashboardDesigner version>\ErrorLog   
Also, send us the sample SYDX with accessible connection string, if possible, so that we can check and provide you a solution.

I just downloaded SyncFusion Dashboard Platform and am having this same issue.  Please advise on how you solved this.  I have the most recent version installed.  I copied my error text below.  I get the same error when trying to open the dashboard in the dashboard server also.  Thank you.

Hello, could you post the resolution for this issue. I am receiving the the error:

"The Dashboard service could not be contacted. There may be a temporary glitch or the server may be down."

I was able to view dashboards previously, but this error started after I published an existing dashboard.

Thank You.

MK Mukil Karunanithi Syncfusion Team April 26, 2017 10:50 AM UTC

Hi Michael, 
 
The exception “The Dashboard Service could not be contacted” is due to connection failed in service or when some other process using the service. So, 
(i)                  Please check whether the IIS is running. 
(ii)                In Browser Address bar, give “DomainName:PortNumber/DashboardService/DashboardService.svc” and ensure whether the service is running.  
(iii)               If you have enabled SSL for the server, then you need to enable the SSL configuration for Dashboard Service too. Please refer to the below link to enable SSL for Dashboard Service. 
 
Regards, 
Mukil K. 


MF Michael Fletcher April 26, 2017 01:59 PM UTC

I have verified the three points that you identified. IIS is is running, the web service is running at DashboardService.svc and SSL is enabled through the configuration tool. The only ports that are running in IIS is the port that was assigned when the dashboard server was installed (64159) and port 443.

I can see two errors listed in the log:

Error Code:-2146233033
System.UriFormatException: Invalid URI: The format of the URI could not be determined.

Hi Michael, 
 
Please share us additional information below, 
i) Which Data Source are you using?   
  
ii)Are you designing the SYDX report in Code view or Design view?   
  
iii) Are you publishing the dashboard from Designer or publishing directly in the Server?  
 
Regards, 
Mukil K.
