After many years of successfully working, I am now unable to access my old Core via Tinker - I get the error “Spark Web”, Authentication Error…
When I log in to the Web IDE, my Core shows connected to the Wifi network and breathing ok, but I am unable to use the ‘flash’ icon. ]
I have tried resetting the Core, resetting the Token and clearing the cache, etc but nothing changes. The Core just has the basic firmware on it, nothing modified although I can’t see which version.
Any help greatfully appreciated or is it just time to buy an Electron??
(As an aside, when I go through the connecting core process, the core blinks flashing green, etc, as it should before breathing light blue - however, Tinker says “unable to find core”.)
Thanks very much,
