Photon cannot connect - rapid blinking cyan [SOLVED]

I can’t get it to stay in safe mode. While following the guide after releasing SETUP my Photon directly goes to SOLID WHITE (~5s) -> BLINKING GREEN (~3s) -> the same as the video above.

I did try to do fix the keys, but I’m afraid I also ran particle keys server. Can that be the problem (that my Photon is trying to connect to a non existing cloud)?

Edit: Followed the instructions here Tutorial: Local Cloud 1st Time instructions [01 Oct 15] to download the cloud_public.der file and updated my Particle with:

particle keys server cloud_public.der 

And now it is working again. Somehow it lost the cloud key.
