Blocked access to generatepress.com from our hosting provider

Hi,

As hosting providers one of our outbound traffic
IP addresses: 51.254.106.82
(a clean address if you check it at https://www.ipvoid.com/ip-blacklist-check/)
is being blocked by gentepress:
——-
root# curl -I https://generatepress.com
curl: (7) Failed to connect to generatepress.com port 443: Connection timed out
——-

We as hosting providers with lots of users using gentepress, We are scared!

Where/Who we can contact?

thanks a lot
