OTA update problem

Hello together,

i have a issue that the updates on my Rasberry Pi 5 and 3B not work. I currently try to update from version 3.703 to versiom 3.785.
I get the following errors:

bad status code 416
failed to retrieve from http://updates.volumio.org/pi/volumio/3.785/volumio_current.sqsh
Aborting, download available in volumio_current.sqsh.part
zsync done

bad status code 416
failed to retrieve from http://updates.volumio.org/pi/volumio/3.785/kernel_current.tar
Aborting, download available in kernel_current.tar.part
zsync done

If i connect via ssh to volumio i can download those files with wget without any problems.

Do you have any hint for me to solve this issue?
