Problem

I uploaded a file and it is not an .e2ee file on the server. But when I try to open it, it does not work.

Solution

There are multiple reasons why this might happen.

For testing, try uploading a file yourself and also downloading to see if it works in general. If not:

• HTTPS: Please check that you are using https protocol for you installation. Browser Webcrypto support is only available when using https.
• Lokal Key Storage: Check in the personal security settings if you have a valid private key.
• Keyserver: Check the connection from the browser to the keyserver.
  

  • Edge: If you are using edge make sure you executed following command in a console (also see https://docs.microsoft.com/en-us/archive/blogs/msgulfcommunity/how-to-debug-localhost-on-microsoft-edge):

    CheckNetIsolation LoopbackExempt -a -n=Microsoft.MicrosoftEdge_8wekyb3d8bbwe REM for Older Edge Versions: CheckNetIsolation LoopbackExempt -a -n=Microsoft.Windows.Spartan_cw5n1h2txyewy

  • Smartcard: Make sure you have your hardware token inserted. You can open the configuration utility to check if en/decryption works
