#1. You can still fly without updating your firmware while to try to figure it out.

#2. What kind of device are you using?

#3. Are you trying to update "DJI GO 4"?

And you might also try to do the update "hardwired", as in using a Lan cable from pc to your modem/router.
Sometimes the signal from the Mavic ac/controller can "blow out" your wifi signal from your router.
I had the exact same issue when I open the box to register my bird, (but not/never updated anything). Once I used the Lan cable (only had to do it once), all was happy happy happy....
