I got the same error after rebooting remotely.
from hypernets_tools.
Is the virtualhub service running?
systemctl status yvirtualhub.service
from hypernets_tools.
I got this:
[hypernets@hypernets-cnr1 hypernets_tools]$ systemctl status yvirtualhub.service
● yvirtualhub.service - Yoctopuce VirtualHub

That looks good. I've seen the 489 error only once and it was fixed after reboot (the Yoctopuce rebooted itself and hence also the rugged PC shortly after that error)
from hypernets_tools.
In my case, the Yoctopuce did not reboot itself after one day. I try to interact with the system, but I get the same error, e.g.,
[hypernets@hypernets-cnr1 hypernets_tools]$ python3 -m hypernets.scripts.relay_command -n3 -soff
init error:Unable to connect to server (ytcp:489)
from hypernets_tools.
@jkuusk, @corizzi, is there a way to reboot the Yoctopuce remotely?
from hypernets_tools.
If you are unable to connect to the yoctopuce then I think only way of rebooting it is power cycling. Unless you can control the power source remotely I think it is not possible to reboot the yoctopuce.

@jkuusk, @clemgoyens, all partners,
From your experience, could this happen on the field? Should we be thinking of a solution, like a remotely controlled switch?
from hypernets_tools.
Yoctopuce itself was supposed to be that switch. In my experience I have not seen such an issue that the yoctopuce is inaccessibe for extended period of time. I've seen occasional errors of not being accessible, I've seen yoctopuce rebooting at random moments, I've seen some commands (switching relays) blocking for nearly 20 minutes.
Can you connect to the yoctopuce web interface from a browser or that one is inaccessible too? Can you ping the yoctopuce?
from hypernets_tools.
Yes, we can ping and connect to the Yoctopuce by the web interface:
[hypernets@hypernets-cnr1 ~]$ ping 127.0.0.1
PING 127.0.0.1 (127.0.0.1) 56(84) bytes of data.
64 bytes from 127.0.0.1: icmp_seq=1 ttl=64 time=0.070 ms
64 bytes from 127.0.0.1: icmp_seq=2 ttl=64 time=0.146 ms
64 bytes from 127.0.0.1: icmp_seq=3 ttl=64 time=0.090 ms
We have a different error now, when pressing the connection button in the gui:
[hypernets@hypernets-cnr1 hypernets_tools]$ python -m hypernets.gui
init error:ytcp:650:tcp(113):No route to host
from hypernets_tools.
You are pinging the localhost. Can you ping the yoctopuce IP from the rugged PC (yoctopuce_ip parameter in the configuration file, probably 10.42.0.something)?
from hypernets_tools.
The last time I encounter this error, I could not ping to 10.42.0.X. I have not encountered this error anymore.
