I have machines on various different subnets. All work except machines on 75.88.18.217/29.

All machines are resolving download.opensuse.org to 195.135.223.226

The problem subnet machines can successfully download index.html from https://download.opensuse.org/repositories/Apache/openSUSE_Leap_15.6/ but timeout when trying to download  http://download.opensuse.org/repositories/Apache:/Modules/openSUSE_Leap_15.6/.

I have performed packet capture at the point of egress from my network, and I see the handshake succeed with 195.135.223.226, but then I get no response from 195.135.223.226 when making a GET request for the failing requests.

I have another public subnet which is working fine, also using 195.135.223.226

Any thoughts?

Thank you,
