Microsoft Edge cannot establish a connection to DocuWare Desktop.
There are several reasons that might cause such an issue:

  1. Install all available Updates for Microsoft Edge.
  2. DocuWare Desktop is not started
    (Re-)Start DocuWare Desktop
    More information on this is available here
  3. DocuWare Desktop Service is not started
    (Re-)Start DocuWare Desktop Service
    More information on this is available here
  4. DocuWare Client is hosted using a self-signed SSL certificate
    The root certificate has to be imported to the Microsoft Certificate Store

  5. Content within the browser cache is causing trouble while trying to establish the connection
    Delete the browser cache and cookies and try it again.
  6. Microsoft Edge does not allow localhost loopback:
    Open Microsoft Edge type "about:flags".
    Check if the "Allow localhost loopback" check box is set:

    Then, start the command prompt (cmd) as administrator and execute the following command:
    CheckNetIsolation LoopbackExempt -a -n=Microsoft.MicrosoftEdge_8wekyb3d8bbwe

  7. DocuWare Settings in Web Client  are not working properly
