Which Mini model are you trying to update?  

Hi, Brauzeuge. Thank you for reaching out. What is the current firmware version of your RC-N1 and which drone are you trying to pair it with? Can you please provide us the exact message? Also, please make sure you have the correct version of DJI Assistant 2 which is the Consumer Drones Series and can be downloaded from this link:  (https://www.dji.com/downloads/so ... sumer-drones-series).

I'm running into an issue with the app and the assistant when I want to upgrade.

My quad is curently at 01.04.0000, but there should be newer firmware for it available. When I check via the app it gives me a long hexadecimal error and on the assistant it throws error 3-401 or 2-0. If this is a HTTP error it simply means I'm unauthorized to read a file from your server.

Someone needs to HUP that server.
Sometimes it does show firmware updates 01.07 and 01.06 I have seen come by, but they never finish downloading always go to 17-23% and then stop.

I have also the exact same issue as the commenter above. I am trying to update the firmware on a newly purchased mini 2 drone. It seems that we are unauthorized or  our http connections to your server are being blocked after downloading about 20%.

Similar problem for me. I cannot connect the server for download. I have mini 2.

"Network error (3-401) Please retry"

I have the ios app at 1.10.1, my remote is the 04.11.0200 version as well, and my flysafe is 01.00.01.29. My mini 2 is 01.06.0200. I just got it today and i am unable to update the drone's firmware with either the app or the dji assistant which gives me network error 3-401. Very, very weird...  

Seems no one knows what is going on. DJI you have any solution to this? Yesterday was working and today all I have is this.

Now I have this. What is going on?

I have the exact errors like you, George. Also trying to update my Mini 2 Firmware.

Also not working over the Fly-App...frustrating.

Same error of George Voicu. Any solution ?

Same issue. Please comment if anyone resolves the problem.

Can't get my p4 to connect to computer or go 4 app for firmware update. Frustrating to say the least, I have a very expensive paperweight/brick, as it will not fly without the firmware update. Just about ready to go back to parrot anafi. Less expensive and no Fly safe restrictions, and no connectivity issues.

Same issue. My DRTK2 has suddenly started assigning random dates to the log files, which is odd. Firmware was fully up to date a couple of weeks ago!

Don't know if it helps, but my issue was resolved by DJI, who asked me to reinstall Assistant 2 from this link: https://www.dji.com/downloads/products/d-rtk-2
That worked for me.
