That's one reason.

Another one is if you have recently moved an IOC onto a different
subnet or to a different IP address. The DNS cache can do weird things
(both on the network/router/DNS server and on the IOC itself) -
I remember seeing similar problems at some point, and you can
probably find that thread in the tech-talk archives searching for
DNS cache.

Aloha,

I believe those are multicast message, i.e. sent to the broadcast address with with a specific port, in this case 5064. I think I have seen that message when some device on the network is not ignorring the multicast as it should, but is replying with a "Connection refused" message. In our case it was a terminal server that was doing that.

Hi

We have a local control net.
This is the first time I run an IOC on it:

I get the following message:

../online_notify.c: CA beacon (send to "172.16.255.255:5065") error was
"Connection refused"

What does this mean? Why is it trying to connect to the broadcast
address?
