"This is not the page you are looking" error

Good evening,

With the latest stable version of deCONZ, after a certain amount of time (I’m not sure how long), I can no longer access the Phoscon web interface. and this message appears :

This is not the page you are looking for
The file /pwa/index.html couldn’t be found.

(404 Not Found)

After a reboot, it works again for a while.

I have tried:

  • clearing the cache
  • incognito mode
  • multiple web browsers
  • using the IP address
  • a complete system reinstallation

Control via Home Assistant and the rules are not affected

System :
deCONZ 2.32.5 on Raspberry Pi.
