The following configurations are always a mystery for me, making me
confused. I think I don't have enough knowledge on them.

EPICS_CA_AUTO_ADDR_LIST=YES
EPICS_CA_ADDR_LIST=localhost

There are two crucial parts of CA name resolution: the name resolution request must reach the server (IOC), and the server's response must reach the client.

EPICS_CA_AUTO_ADDR_LIST
    YES (default): Send name resolution requests as UDP broadcasts on all known network interfaces except loopback (localhost).
    NO: Don't send name resolution requests as UDP broadcasts.

EPICS_CA_AUTO_ADDR_LIST
    In addition to doing the UDP broadcasts (or not, see above), send UDP name resolution requests to all addresses in this list.

Cheers,
