If you installed an early Beta version of this OS and upgraded to "25.04.1" or higher and unable to access HexOS dashboard etc?
you may have some services that are broken
login locally into truenas, go to the shell
Fix: sudo python /usr/lib/python3/dist-packages/middlewared/scripts/vendor_service.py (reboot)
Reboot and still broken?
sudo systemctl restart websocat
