Website unreachable

I have been set up, but keybase says Website unreachable . Please help me. Thanks.

Account belonging to https://keybase.io/kelvintu

Here's the proof of my website Check out Mr Kelvintu(@Kelvintu):
http://www.boardware.com.mo/keybase.txt
http://www.boardware.com.mo/.well-known/keybase.txt

Start by checking the two listed keybase.txt URLs and the account proof for kelvintu, then determine why Keybase reports the website as unreachable. Done would mean identifying the verification failure and confirming that the account's website proof is reachable and accepted.
