I2C connection error

[ThEnGI]

I cant work my rig, i think there is a i2c problem, i cheked the board and is connected right (the led powers on).
I'm an elettronic so i have very little C programming ability...
I have used the lastes library (downloaded yesterday)

The arduino works fine, 3 tried whit BLINK and one coming from another project, The esp32 also work fine becouse i used it for direct mining before. tried to flash everithyng multiples time: no solution.
One time it have worked (so so) but no work has started just a cicling connecting, no timeout
i tried to chanmge the level converter whit a new one no solution, also tried whit less arduino's (even just one) no solution
As picture: the circuit is composed ESP-32 -> Logic level converter -> 4*Arduino Nano. The power come from the usb of the ESP-32 then delivered to arduino.

The serial monitor output:

rst:0x1 (POWERON_RESET),boot:0x13 (SPI_FAST_FLASH_BOOT)

re check connection and LL connection, evrityng is correct.
Tried an old versione and che I2C works fine, the arduino is see by the ESP32 but i get unable to connect to duocoin server..... (is an old version so is normal :-) )
I think is a bug of this version 2.7.3.....

Is possible to use another pin (+resistor + led) other then led_builtin ? my esp32 dont have it !!

Output of the old version:
[0]Connecting to Duino-Coin server... with port 6002
[0]Connection failed.

Any news? I have the same problem, did you get this to work?

And also, have not the urlPool changed to https://server.duinocoin.com/getPool from http://51.15.127.80:4242/getPool?

Hi, I am on the same error since 2.7.3.
For the moment my rig works fine with A lab power supply. Not working like that with a normal USB-Power supply as it has done before 2.7.3. So maybe it is a problem in the power supply, like noise or instability.
