We changed the IP addresses in our lab recently and afterwards the Newfocus motor mirror could not communicate with ARTIQ. ARTIQ itself is running without issue. After restarting the Windows PC, I can reach the mirror controller with a normal ping in a shell and I also can connect to it successfully with the Newfocus software and read e.g. the device ID. When starting artiq_ctlmgr, I receive an error after some time, though:
WARNING:controller(motor1):newfocus8742.protocol:ping failed

The device_db entry for this device is:
"motor1": {
"type": "controller",
"host": "::1",
"port": 3268,
"command": "aqctl_newfocus8742 -p {port} --bind {bind} --tcp c19967"
}
Changing the name in the network to the static IP did not fix the issue. If I run an instance of the sipyco server with aqctl_newfocus8742 -p 3268 --tcp c19967 and talk to the server with sipyco_rpctool ::1 3268 ping from a separate shell, I get the following error on the server:

Before the network changes, I could use the mirror motor with the same configuration without issue, but I don't see immediately how this error is related to that. Other controllers, such as influx_db and core_moninj do not show this behaviour. I also power-cycled the mirror controller itself, but this did not change the error. How can I fix this issue?
