Nuki 3.0 Pro looses connection despite AP is next to it

[Romano_Augusto]

Since couple hours no error so its fixed?
Added beta yesterday

[Deff99 (Tim)]

Jup, still connected.

[alan.malone]

So strange. I’ve had a consistent connection all afternoon after reconnecting earlier. I have yet to be accepted in beta, so still on 3.4.9.

Makes me wonder if there was some change on the server side?!

[Romano_Augusto]

Im connected for a couple hours now without in app errors , how about u?

Bei Nuki für die Smart Lock Beta angemeldet ,freigeschaltet worden .
Manuell Firmware installiert ,keine Probleme mehr mit der neuesten Firmware

Same here, I already traced the issue to the lock trying to contact sse*.nuki.io and which seemed unsuccesful causing a reconnect loop with your home wifi. Since a couple of hours the issue is gone. It’s obviously a cloud issue at Nuki side.

[Phuturist]

For me it’s still not keeping a persistent connection. I can see it’s reconnecting often and the connection quality is very poor (around -50 dBm RSSI) even though there is an access point right next to it. The reconnection process ends with the SSE server that can not be reached (you can see this info by pressing 7x on the network header under the WiFi settings). I’m curious if more people are seeing the same.

Came from public release to beta 5.3.2 in hope to get rid off issues with wifi connection, yet it did not resolve… I have Unifi system (no changes in settings) but since last public release my wifi connection keeps disconecting on the lock…

Plus, I am unable to click on the title to enable debug, as the title is not visible? Or am I missing something?

The Apps UI has been reworked with the last release. To enable debug you have to Smart Lock > Settings > Features & Configuration > Tap 7x on the “Features & Configuration” headline.

There is a new beta available:

Smart Lock Firmware 3.5.x Beta

Firmware 3.5.3 has just been released. It stabilizes the WiFi connection in most of our testing setups significantly. Please give it a go and report back in this thread any experiences. It might not solve the problems with some Unifi setups where the Smart Lock does not reconnect to Wifi anymore after some time. If you are affected and your Smart Lock does not automatically reconnect, please try to access it via BLE, unlock the door via button or manually by turning the knob on the Smart Lock a…

Same issue here since bought. I have created label for return it.

Tried different APs, reseted many times, just updated to 3.5.10 and same problem without solution.

Too expensive for so big issue.

[Phuturist]

Are you on a Unifi network setup. It would be nice to identify a pattern.

[tampiss]

I am on Unifi and all seems working pretty nicely with the latest beta. M

@Juergen could you elaborate on what the Nuki SL3 Pro does when trying to establish a WiFi connection, specifically the step when it’s trying to connect to the SSE server. I have tried every thing to fix the unstable connection of my SL3 Pro but at certain times it just keeps failing to keep a connection and the debug wifi log tells me it’s either trying or has failed to create a SSE connection. I’d like to understand what is happening.

[Javier_Fernandez (Javier Fernández)]

I must say that after update to 3.4.10, reset SL and App and connect it to a guest wifi, it is working perfectly now.

Nuki SL3 Pro does when trying to establish a WiFi connection, specifically the step when it’s trying to connect to the SSE server

There is nothing specific. It does the usual steps that any other product does when starting up WIFI and connecting to a server: scan for wifi accesspoint > join & authenticate to wifi > get an ip via dhcp > resolve ip of nuki server via dns > open tcp socket to ip of nuki server > establish secure SSL link > start to transfer data.

Your case is specific and different than all others because it works for some hours perfectly fine and then completely stops to work and then comes back after some hours, while usually stability problems result in frequent reconnects. → Therefore it does not make sense to discuss your issues here in the forum. Should be done either via DM or with Nuki support.

[myreczek (Mirek Lauš)]

I can confirm that.

Reporting back here in case anyone is experiencing the same. The issue is caused by a Unifi UAC-U6-LR access point. Replacing this with a Unifi UAC-AP-Pro resolved the reconnection issue instantly. Apparently the Nuki SL 3 Pro doesnt play nice with this access point.

I’ve got nanoHD and the same problem.

Hi,
we have a Unifi-Network at Home with a DreamMachine-Pro and four UAP-AC-M’s.

The new SL3 Pro loses the Wifi-Connection every few minutes.

Du you know a solutaion or a helpful configuration in the CloudKey?
