Connect Server UI

The Connect Server is only accessible locally on the host

Check the firewall settings of the host on which the Connect Server was installed. Incoming connections may be blocked.

The Connect Server keeps crashing with an error message that indicates an invalid language key

This is a bug in the original version of the .NET 5.0 Framework. Ensure that at least version 5.0.4 of the .NET Framework is installed and that there are no preview versions of Visual Studio 2019 on the host.

The Connect Server is available, but only the text "Loading..." is displayed without the page being loaded

Please check whether the browser you are using supports WebAssemby. For Chrome, for example, at least version 57 is required.

Error message "Login failed: Network error" is displayed when logging in

This error occurs when the HTML pages of the Connect Server are accessed via HTTPS, but try to communicate with the backend services via HTTP. This may happen if the Connect Server is configured for HTTP and the user is accessing it via proxy server using HTTPS.

Configure the Connect Server for encrypted end-to-end communication via HTTPS. To do so, create an appropriate HTTPS endpoint. For more information, see the User Manual.

Analysis of various UI problems

If the frontend reports that an error has occurred, you can press F12 in a Chromium-based browser (e.g., Chrome or Edge) to open the developer tools. Error messages can be viewed in the "Console" tab.
