Can't reach addic7ed.com from my home IP

[grutgrut]

Hi,

Suddenly, from home, i haven't been able to reach addic7ed.com. It was working and it stopped...

DNS resolution is OK, pinging is OK, but when i try to reach it thru curl or web browser (chrome, FF, whatever you want..).

I tried from my laptop, my wife's one, my phone... epic failed.
I rebooted my router, switch, everything you can think of.. failed...

Here what curl tells me :
curl: (7) Failed to connect to www.addic7ted.com port 443: Connection refused

I tried using my phone data plan, no problem it works. From a server i have at home, no problem.

So it's really from my IP.

Is there some kind of IP ban...?

Thanks for the help!
