Since yesterday, all 4 Photons and a Core in my household have stopped connecting. I resetted them, resetted the router and modem but they won’t connect. They keep flashing cyan with the occasional 3 flashes of orange. I have tried connecting one of them through another internet connection/provider (wifi tether) but it did not work either, excluding problems with my network.
I have flashed tinker using ‘particle flash --usb tinker’ through DFU and I have also run particle keys doctor with the following result:
C:\Users???>particle keys doctor ???
New Key Created!
attempting to add a new public key for device ???
submitting public key succeeded!
Okay! New keys in place, your device should restart.
I tried setting the wifi credentials again, and this resulted in the application going through all the steps and stopping in the “checking connectivity” stage. The led is now blinking cyan (on the device I am testing on).
My Particle account seems to be fine since I can connect to the console without problems (using 2FA).
I find it odd that all 5 devices decided to stop working simultaneously.
UPDATE: It appears that when I try to connect through a different internet service provider (I tried with another two) it works fine (contrary to what was stated earlier. However, when I tried connecting through a different network but same ISP as my own (Melita) the cloud connection fails. Is it possible that the ISP all of a sudden started blocking access to the particle cloud servers? Is there anything specific that I need to have them check? Up until they were blaming my router, which is clearly not the case since I had the same problem with someone else’s Melita modem. So I need to give them all the information they might need to pinpoint the choke point.
UPDATE - The devices started working again on their own this morning. I guess the ISP realized what they did when the problem started and fixed it.
