The given key was not present in the dictionary

You open the Lansweeper web console, and you see an error “ The given key is not present in the Directory”

Now what?

The error The given key was not present in the dictionary is rather generic and can have multiple causes.

To ensure the issue is not caused by an incorrect, corrupt or missing website file, we recommend clearing the ASP.NET cache, which may already resolve the issue.
Stop your webserver service. Your webserver service is either World Wide Web Publishing Service (IIS) or IIS Express.
Empty the folders listed below.
- C:\WINDOWS\Microsoft.NET\Framework\v4.0.30319\Temporary ASP.NET Files
- C:\WINDOWS\Microsoft.NET\Framework64\v4.0.30319\Temporary ASP.NET Files

Restart the webserver service
Test the web console

Not fixed?

If the issue persists, there may be an issue with the page itself. We would recommend reinstalling the web console.
