handle_probe_req: Send failed

[handleprobereq]

Hello, I am trying to host an AP with captive portal (Option 2 from your script) with:

alfa awus036nha atheros ar9271

And I am getting this error:

I tried to google it, but I can't find anything on it.
The AP works for a while then I get the error, when the error happens then I can't to connect to the AP anymore.
