Version 3.2 is a bit old, thanks for your reply;
Of course, we've tried ping, nslookup, all of which recognize the DNS,

Can other utilities resolve the name correctly (e.g. ping, nslookup)?
3.2 is very old. Try a newer version and see if it still doesn't work.
If it doesn't, build it with --enable-debug option and post output from chronyd -d -d.
