I can not download the firmware update

Hi . I can not update the firmware in the WD blue SSD with the WD Dashboard 2.5.0 . Advise me that new firmware is available , and then I click on Update SSD Firmware button ,
at first it starts to download something, but in 2 or 3 seconds it stops downloading (I know it through the router lights), and the download assistant continues for a while until it finally says that there has been an error downloading. This is happening to me with version 2.5.0 of the WD SSD Dashboard

any solution? Thank you
