Failure in final step of WiFi connection

Troubleshooting
1

Hello folks,

When my Photon is in the last step of connecting to the WiiFi network (i.e. fast cyan flashing) it fails. It blinks yellow/ / red (see video below) and it returns to flashing cyan again. It stays in this look indefinitely without connecting to the cloud.

I have try to setup the Photon using the mobile App and passing the credentials through serial mode. I have also installed 0.4.5 through DFU successfully.

Any ideas what is going on or how to connect the Photon to the cloud?

Thanks!

I’m guessing your keys got corrupted somehow. Would you be willing to try this?

Hi @Moors7,

I tried to use the keys doctor but I’m getting the following error:

C:\Users\sergio>particle keys doctor 22002a00154734XXXXXXX

Make sure your device is in DFU mode (blinking yellow), and that your computer is online.

I ran npm update -g particle-cli and tried again but no luck. Any tips? Thanks!

@sazp96, did you install openssl on your system?

No I hadn’t. Now I have :smile:

Now I’m getting the following error when trying to save the key to the Photon.

i have the same problem with one of my photon. glad i found this post. running particle keys doctor solve everything. the photon suddenly restart and act like nothing happening at all. my device name is back (although i already unclaim the device through web IDE), my last firmware that i flashed is back. funny.
anyway thank you Moors7 & peekay123!
