How to set up a local server for debugging without disconnects?

Options

I wanted to set up a local server for debugging according to this article https://doc.photonengine.com/en-us/server/current/operations/debugging

 But when you try to connect to the local server, an error occurs.

OperationException: Plugin Mismatch requested='FusionPlugin' got ErrorPlugin with message:'PluginFactory: Can not find plugin with name:'FusionPlugin'

PUN connects to the same server without error
