Hi to all

I have a WinCC Professionnal V17 project currently running with Web Navigator.

Clients are connecting using WebViewerRT, in http, and it works correctly.

I have configured IIS to use https (and added a certificate). When I connect using WebViewerRT, after typing user and password, after the message "Loading Picture" I get the error message : "Failed to load https://siteurl/Start.PD_"

Any ideas on how to solve this issue ?

Thanks in advance

Hi v.boue,

I recommend to check this FAQ:

What can you do if the WebNavigator or DataMonitor client does not connect to the server?

Hi,

In addition to the mentioned FAQ, maybe you can check for the following possible causes:

- If you are using encrypted communication (https) and a Windows server operating system, make sure that "Do not save encrypted pages to disk" is deactivated in the Internet Explorer settings (Tools > Internet Options > Advanced > Security / Tools > Internet Options > Advanced > Security > "Do not save encrypted pages to disk").

- Erroneous group policies. See FAQ: "Exceptions for hardening measures according to CIS"

- Incorrect permissions for the screen or the "Web Navigator" folder. If necessary, delete the folder in the project directory and republish the images. The Security Controller should also be re-executed.

- Problems with the IIS/WebNavigator Server. Try accessing directly locally, on the Web Server itself.
