I bought two breakout boards for the imp003 from Tindie when they came out, and have been using one ever since I got it.
I recently unpacked the second one which I kept on a shelf for years and never powered on up until now, and though the wi-fi connection succeeds (short green blink), it won’t reach the server (long orange, short red flashes).
I have tried from different wi-fi networks and locations, even from a hotspot from my iPhone sharing its 4G, with no success, and to my knowledge nothing blocks port TCP 31314.
Is it possible that your servers no longer accept connections from very early firmwares ?
Many thanks for your insights,
