I think I got attacked by someone. And my site can't load. I already try to rerun the loophole many times. Still got attacked and my loophole response was everytime I run it,

"TLS Certificate failed to provision. Will be obtained with first request made by any client, therefore first execution may be slower."

??? http: TLS handshake error from 127.0.0.1:<unknown_port>: tls: received record with version 301 when expecting version 303

Then I got so many of,

Succeeded to accept connection over HTTPS

This was like spammed.

So, I have two questions,

1. How to avoid from my site got attacked from unknown attacker?

2. How to fix the "TLS Certificate failed to provision"?

Sorry if I'm English not quite good.
