My home firewall must be, since other remote systems work fine.
How can I test whether it is open on the server? I assume telnet 123 uses tcp.
How do I send a udp packet to test whether it gets through?
The server is behind a university firewall. The claim is that that firewall
lets through udp on port 123. Mind you telnet S 123 gets through so that would
suggest that tcp gets through, if I am right that telnet uses tcp.

NTP is a UDP protocol. Is your firewall open for UDP port 123 ?

Note that I use other servers (eg a pool server) from my chrony on H, and they
work fine
so again it does not seem to be a problem with the firewalls/routers between H
and the internet.
NTP is a UDP protocol. Is your firewall open for UDP port 123 at both client
and server?
