Can't update Operating System 3.3

I installed HA to pi4 and long time can’t update from Operating System 3.3 to any new version. Now to 3.10.
Got error:

20-02-15 15:55:28 WARNING (MainThread) [hassio.hassos] Can't fetch versions from https://github.com/home-assistant/operating-system/releases/download/3.10/hassos_rpi4-3.10.raucb:

  File "/usr/src/hassio/hassio/hassos.py", line 110, in _download_raucb
    raise HassOSUpdateError()
