Hi Christian,

This error occurs when attempting to decrypt an encrypted string using the wrong encryption key. The encryption keys are stored in the `<appSettings>` section of server configuration file:

```auto
 <add key="Continua.HashSalt" value="***"/> 
 <add key="Continua.SymmetricEncryptionKey" value="***"/>
 <add key="Continua.SymmetricEncryptionVector" value="***"/>

```

When migrating ensure that these keys are copied from the old server to the new server.

The sever configuration file is located at \<continua\_install\_path\>\Server\Continua.Server.Service.config. By default, this is at %ProgramFiles%\VSoft Technologies\ContinuaCI\Server

Note that this file also contains the connection string for the database.
