No longer able to flash updated ESPHome versions: Error: Authentication invalid. Is the password correct?

[louispires]

I flashed this well over a year ago, worked great until about August last year when the ESPHome firmware no longer flashed successfully via OTA.

I tried playing around with the OTA Password field etc. but nothing seems to have worked and I am now stuck on an old version

Will probably need to sort this out soon due to the deprecation of the ezsp and seems like xsp1989 is busy attempting a new firmware build

Ideally, I would not like to resolder again and prefer to be able to do an OTA of some sort.

Any recommendations?

You are on the right track. You have to find out the OTA password or key you have used last time to flash the device. Did you migrate to the encryption key already or did you flash the device using an OTA password last time? If you are unable to find out the password you cannot flash the device using OTA. Soldering to flash the ESP using an UART connection would be the only option I'm aware of.

I had never added an OTA password, it just randomly one day stated that the password was incorrect.

That is when I started experimenting with adding a value and even attempting to set the password on boot:

on_boot:
    - lambda: |-
        id(my_ota).set_auth_password("New password");

Which also did not work for me...

Do you agree to close the issue?
