I am unable to decrypt my own uploaded files with e2ee

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.

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

If none of the above worked, please contact support.
