Unable to find valid license key.

Hello,

I've got an issue with my own server. Indeed, my friends cannot connect into my server. I dont have a NPL licence. I just use my PC to create a local server.

there's the log:

I have already checked several topics with the same problem as mine. But they all use a NPL which I dont.
