No free leases

I have a small test network and a dhcp server that was working for it 
previously, and is currently working for other, similar, production 
networks.  After bringing the test network back up, the dhcp server is 
saying "no free leases" for no apparent reason, and I'm hoping someone 
can point me at the problem:

Config:

subnet 207.55.34.16 netmask 255.255.255.240 {
   option routers 207.55.34.17;
   option broadcast-address 207.55.34.31;
   option domain-name-servers 69.59.192.61, 69.59.192.62;

   pool {
     max-lease-time 300; # 5 minutes for debugging
     range 207.55.34.20 207.55.34.28;
   }
}

All the leases are free:

lease 207.55.34.20 {
   starts 3 2021/04/07 16:30:12;
   ends 3 2021/04/07 16:35:12;
   tsfp 3 2021/04/07 16:37:42;
   atsfp 3 2021/04/07 16:37:42;
   binding state free;
   hardware ethernet 48:77:46:f9:5b:b0;
   set vendor-string = "GS4220E.ONT.dslforum.org";
}
lease 207.55.34.25 {
   starts 3 2021/04/07 16:35:22;
   ends 3 2021/04/07 16:35:25;
   tsfp 3 2021/04/07 16:35:25;
   atsfp 3 2021/04/07 16:35:25;
   binding state free;
   hardware ethernet 48:77:46:f9:5b:b0;
}
lease 207.55.34.26 {
   starts 3 2021/04/07 16:36:26;
   ends 3 2021/04/07 16:36:29;
   tsfp 3 2021/04/07 16:36:29;
   atsfp 3 2021/04/07 16:36:29;
   binding state free;
   hardware ethernet 48:77:46:f9:5b:b0;
}
lease 207.55.34.24 {
   starts 4 2022/01/06 22:14:35;
   ends 4 2022/01/06 22:19:35;
   binding state free;
   hardware ethernet d0:76:8f:6f:dc:15;
   set vendor-string = "GS4220E.ONT.dslforum.org";
}
lease 207.55.34.27 {
   starts 6 2022/03/12 00:51:18;
   ends 6 2022/03/12 00:56:18;
   binding state free;
   hardware ethernet 48:77:46:f9:5b:b0;
   set vendor-string = "GS4220E.ONT.dslforum.org";
}


 From the log file:

Aug 23 14:28:20 dhcp01-u dhcpd[3044108]: DHCPDISCOVER from 
f8:85:f9:2b:87:19 via 207.55.34.17: network 207.55.34.16/28: no free leases
