This looks like the issue:

Nov 22 23:10:03 rkhstudy kernel: lockd: server 192.168.1.2 not responding,
still trying

This was working fine in Fedora 32, though, so I'm puzzled what's wrong now.
There's no firewall on the client, and nothing has changed on the server,
and I do not see any error messages there. Is lockd perhaps using a
different port, which is blocked on the server? If so, how do I find out
what that is?

'rpcinfo -p' should tell you port numbers, although it's usually
something in the firewall that causes the issue.

Yes, thank you, that is definitely the problem. Disabling the firewall on the server solves it. (Disabling the firewall on the client has no effect.) But of course that's not a long-term solution, and I'm still puzzled why this is failing after the upgrade but was working before.... I found a few relevant pages on the web, but they tell me to enable services in the firewall that are already enabled.

Here's the firewall on the server:

# firewall-cmd --list-all
public (active)
  target: default
  icmp-block-inversion: no
  interfaces: enp2s0
  sources:
  services: dhcpv6-client mountd nfs rpc-bind ssh
  ports: 9000/tcp 9000/udp 3483/tcp 3483/udp 9090/tcp 9090/udp 1900/tcp 1900/udp
  protocols:
  masquerade: no
  forward-ports:
  source-ports:
  icmp-blocks:
  rich rules:

I restarted it in case something was wonky. No effect.

If you are using nfs-V3 you need to enable the nfs3 service in the active zone.

I haven't used nfs-V3 in a long time.  However, I seem to remember that if you allow nfs3 in
the services there is no need to define open ports as that is taken care of.

Thanks for the suggestion. Unfortunately, it does not seem to help. It still seems weird to me that it worked with F32 and now not with F33. What could have changed on that end?

I will check later with a machine still running F32 that it does still work there.
