Hi,

Further debugging indicates that the host used to download data from
launchpad's API is blacklisted somehow on the launchpad side.

It's ullmann.debian.org / 2607:f8f0:614:1::1274:38
And the problem started happening on 2025-12-19.

$ tcptraceroute6 2620:2d:4000:1009::3ba 443
traceroute to 2620:2d:4000:1009::3ba (2620:2d:4000:1009::3ba) from

It works over IPv4, but I'd rather not ignore IPv6 on the client side.

I believe the behaviour of the script is sane.

Any help with getting it unblacklisted on the Canonical/Launchpad side
would be very welcomed.
