Simple macaroon token request takes 30s?! You should probably start with
this issue ... actually this is pretty simple, your IPv6 connectivity is
broken and this could bring with a lot of fun especially with old HTTP
libraries like libneon that are still in by KEK FTS server (actually for
better IPv6 support it would be necessary to enable `curl` for FTS/gfal
and run FTS on EL8 or EL9 and that OS version is not yet officially
supported).
# routing works fine to your PerfSonar which is on same subnet

You should really fix HTTP-TPC pull mode, which should be preferred
(btw: FTS developers now considering changes in FTS that will prevent
automatic fallback push <-> pull in case one method doesn't work,
because this functionality just hides serious site issues and makes
HTTP-TPC transfers debugging unnecessary complex)
