my fault. the system i mentioned in the original question "FreeBSD 12.2" is the ssh server. for this case, the system which i used as the client is also FreeBSD 12.2. test from other host(from different network ) as the client to ssh to the " 2607:f130::6287", it's the same issue. test from the localhost (the host config the ipv6 address as 2607:f130::628 ), use the command: %ssh myuser@2607:f130::628, it's work well. I don't know what is the problem, how to fix.
