config not accessible after firmware upload

Hi there, I need a little help.

I have a wemos D1 and after the firmware upload (flash) I can connect to the ESP_0 wifi network.
but I don't get the config page. If I try directly 192.168.4.1 in the browser there is no response.

I get an IP-Address from the wemos D1 (192.168.4.2) and see that the gateway (wemos) has IP 192.168.4.1

Using the ESPEasy_120_4096 build, flashing with the supplied flash tool on a windows 10 machine.
Put GPIOo (D3) to GND before power-up and flash. and after flash opened the GPIO0 to GND link and rebooted.

I have tried 2 wemos so far, but no luck

I have already one working did that one a few months a go. Back then I had the same issues. got that one to work but never figured out what the problem was.

Thanks,

I would try espeasy 2.0 dev11 as i know it handles flash a little different than 1.20. (config pages on SPIFFS)

Also sometimes a flash erase before reflash can lead to the expected working mode.

I experienced that after upgrading from Espeasy to Tasmota (without flash erase), some settings remained, like the SSID name, so my Tasmota flashed Sonoff Touch switch advertised itself as ESP_0 at first start. :)

If you have a Wemos D1 mini you don't need to connect GPIO0 to GND in order to flash it as the module contains the USB-2-UART circuit (using the CH340G).
I have always flashed those modules just connecting them via USB to my PC.

I have successfully configured 2 module to the esp 2.0 version.
In the beginning, I had the same problems. But switched to another laptop with windows 7 instead of windows 10
This solves the problem for now.

Thank you for all your advice.
