Helium Router IP does not update until miner reboot (or is too long for updating)

[disk91]

After moving a helium router (console) to a different server with a different IP address, the hotspot fleet still use the previous IP address even 24h later. this prevent the LoRaWan traffic to be routed. Devices lost communications.

When a hotspot is rebooted it immediately take the new router/console address and the communication is restored... but we can't reboot all the hostpots to get the tables updated.

Apparently some miners have been updated with the new IP about 30h after the change. I now see two miners getting the messages. The problem is now the refresh time.
