Can't connect

I have a Netbiter ec301, rev 1.2.2.
I can browse to the webpage, but can’t connect through QuickConnect.
The QuickConnect project was set up and working by an integrator but hasn’t been used in probably 4 years.
I downloaded the latest firmware and tried to update the firmware on the web browser, but I keep getting “error, failed to execute”.

Hello,

Which firmware file do you use?

If you are updating from 1.2.2, you will need to first upload the firmware file of 1.4.5-1.8.1, then you can upload the lasted firmware files.
