Sonoff Classic - works with USB not 230V
My Sonoff flashed with ESPEasy connects perfectly with with the WIFI network when powered with USB/GPIO. However, when i connect to 230V not much happens. Any advice where to start troubleshooting?

I noticed a similar case when going from the AT firmware to easyesp. Its a power supply issue. My guess is that during initial wifi setup the easyesp uses more cpu and the system is producing more curent spikes.
try adding a 100µF tantalum cap to the +3.3V

And what is Sonoff Classic ??
Maybe you connect mains to output, not input.
Bad soldered input terminals.
Measure 3.3V on programming pins with mains connected.
Or if you test with USB on your table and with power line Sonoff laying on floor, it can be issue too.
