build.geoserver.org blocking my IP (185.131.217.78)

Hi, my home IP 185.131.217.78 seems to be blocked by build.geoserver.org (149.56.147.154). TCP connections on ports 80 and 443 time out. A TCP traceroute on port 443 reaches OVH’s network (last reply from 198.27.73.204) and then goes silent. The same machine works fine over mobile data, so it looks like a fail2ban or firewall block on the server side. Could someone check and unblock it? Thanks!
