I am trying to flash a new ESP8266, but when connecting it to my server using USB, after the compile phase I am having the following error:

A fatal error occurred: Failed to connect to ESP8266: Timed out waiting for packet header
Any idea of what the problem might be? the usb cable i am using seems to be fine, tested it by connecting my phone to my pc and I am able to read the phone contents.
EDIT: Problem solved. Apparently the USB port selected in the top right drop down menu was not the correct one. Had to restart ESPHOME add-on while the ESP8266 was plugged in my server, and a new port appeared. Selected this new port and all worked fine.
