preheat temperature not seen

[jcourrege]

Hello, I m expecting a problem in Octoscreen .
Everything is working fine but when I m going to preheat menu, after few seconds I have only :
All Off.

In log, I saw that :
time="2022-09-17T20:14:31+02:00" level=error msg=" TemperaturePresetsPanel.getTemperaturePresets() - Do(SettingsRequest) returned an error: "Get http://localhost:5000/api/settings: net/http: request canceled (Client.Timeout exceeded while awaiting headers)"" file=logger.go func=logger.LogError line=121

How can I fix that ?
Thanks for your help.
