I did a manual update of my Router and Satellites with Tech Support. The iPhone app is now useless. The Network Map shows only my Router and two of my three Satellites. When I go to the Device Manager tab, I get an error message - "Could not reach server. Try again later (code: CDIL-API-FAIL)". The app also does not show the number of Connected Devices as it did in the past. The app is also running extremely slow - much slower than before the update. It says "loading" for quite a while before opening any tab.

Due to the poor and drawn out support and the fact Netgear will not take the ownership of creating the problem with the upgrade of the app, we can not function any longer as a home business with this expensive junk from Netgear.We have removed this equipment and replaced it with working flawlessly equipment from a competitor. I will never use or recommend Netgear to anyone. Since it is in warranty, I should get a refund or a new replacement of my router and extender. This was good money throwed away.

MR80. Same issue. It is on both the iPhone app and the Android app. The only way to permit new devices access is to use the web interface. The app is broken. I have 63 devices and wonder if there isn’t a timeout issue communicating with the app.

Just chiming in to make note that I'm having the same issue as reported by others in this thread. MR80 via the app (iOS) errors out when trying to view devices via Devices or Network Map of 41 devices - CDIL-API-FAIL. Previously had no problems with this many devices. The web interface has no such issue and works just fine. I'll monitor thread for possible solutions from Netgear.

Try a uninstall of the app, reboot mobile device, then re-install app.Try a factory reset on the router unit and setup from scratch using a wired PC and web browser, once fully setup, log back in to all and check devices.

I did uninstall the app, restart my iPhone and then reinstalled the app. Both my iPhone and iPad are still having the same problem. I just did a factory reset with Tech Support - after we did that, this problem started. They had no solution. Why would the web app make a difference?

    Wouls help to get the system setup first using the routers web page, then after its setup, the NH may work after that. If not, NG support will need to pass this to the app team for review.

I am having the same issue as others where after the router update, now the nighthawk app does not work. Netgear support and products are useless pieces of ----. You cannot get any help to resolve the issue. Also netgear routers are widely known for their back door access. Really no privacy or security.

  What about this place?
  
  I see no sign that you have tried to get help anywhere else in this community.
  
  You have joined in on an old discussion about different hardware. (Apps and firmware are linked together.) So it might be worth beginning afresh.
  
  We'll need a detailed description of your problems and your network before anyone can begin to guess as to what might be going wrong at your end.
  
  The R6400 in your footer isn't one of the usual suspects on the troublemaker front. It has been around since 2015 and has had time to bed down.
