Mobotix M73 Unresponsive – 408 Timeout on Reboot and No Live Image

Hello Mobotix Community,

We’re experiencing an issue with a Mobotix M73 camera (firmware: MX-V7.3.4.23-r3) that has become unresponsive.

  • The camera appears as down in our Hub Management system.
  • When we attempt any action—such as reboot, reset, or configuration changes—we get this error:

“408 Request Timeout – Please reload the form without submitting CGI parameters.”

  • We can still access the camera via its IP address through the web interface, but no image is displayed on the live view.
  • The system log also shows multiple critical errors:

E 2025-05-04 10:28:17 STATUS rcontrol Error notification acknowledged by user ‘admin’.

At this point, the camera no longer responds to any control actions, and remote recovery appears to be blocked.

Has anyone encountered a similar issue with the M73 or this firmware version? Any help or suggestions would be highly appreciated.
