My IP has been blocked

Good morning.

I'd like to report issue with accessing your wiki (wiki.debian.org) from my home IP address 213.254.181.9

I get below response:
Forbidden

<p>You are not allowed to access this!</p>

In addition, may I know the reason why I was put on block list? I am learning Debian and it was working fine until couple of days ago.

In the meantime I use proton VPN to access the wiki.

Thank you

Kind regards
Mateusz Belzak
