Friend is having trouble connecting to my server

[Deadzone]

When she tries to join, she tells me that it disconnects saying that it couldn't verify her Id. (I bought her the key, so she's legal)
I'm sure that the fact that I'm currently hosting with Upnp has something to do with it.

Here's the console for when she tried to join:

I'd say it might be a firewall issue, make sure that blockland is set up as an "exception" or similar on her firewall.

Seems to most likely be an issue on his side.

Unfortunately it already is. :c
