Hello, we have temperature-machine installed on three Raspberry Pi 4 Model B Rev 1.5s, two as clients and one as the server.
I am intermittently getting the following error in the temperature-machine.log file:
2023-07-26 09:02:51:223+0100 [temperature-reading-thread-1] ERROR An error occurred executed a scheduled task (RecordTemperature(bad.robot.temperature.ds18b20.SensorReader@1363df7,HttpUpload(temp-wareh/127.0.0.1,Client(Kleisli(org.http4s.client.blaze.BlazeClient$$$Lambda$732/20340783@e93c),IO$16419391)),bad.robot.temperature:DEBUG in 4c12b6)) Could not initialize class bad.robot.temperature.IpAddress$
The device is reachable over the network, it's connected via wifi and ifconfig shows the following:
I understand that this could be related to the content of the hosts file, so here is the contents of that:
pi@temp-wareh:~ $ more /etc/hosts 127.0.0.1 temp-wareh
The symptoms seem to vary, but right now when I browse to the server it shows the temperatures from the two clients, but not from itself. The hardware is fine as I can read the DS18B20 directly:
