Hi there, I am so sorry to open another thread on this subject, but after going through all the troubleshooting forum & support docs, I’m still stuck with my core not connected / unresponsive!

We had some issues with spark keys doctor recently but i’m surprised that spark keys load keys.der didn’t work for you… hmmmm… BTW, what are you trying to resolve? I hope it’s fixed? You can email your public_keys file to @Dave ( david@spark.io ) for a manual update for now along with your core id…
