Firmware (beta) disappeared from the check for new firmware menu



I tried to update to Fw I changed the URL to /beta path, checked for new firmware and the update appeared and gave me the option to update the base.

I then clicked to update but nothing happened for at least 10 minutes.
Then I refreshed the page and clicked again to check for new update and tried again to update, nothing like the last time.

Then I clicked again to check for new update and the update disappeared like I have the stable path although I have the /beta path in the settings.

How can I update manually the DP750/720 to the latest beta version?

Thank you.


the version you indicate is a Beta version, it should not be used in production, however look here:


Thank you! I understand the risk but I have to know if the bugfix #6 is fixing my problem.
