I would like to extend the maximum number of characters allowed in a line from 80 to 120 in my python files (or simply ignore E501 in flake8 altogether). I have a flake8 config file ~/.config8/flake8, which contains
[flake8]
ignore = E501
max-line-length = 120
However, both inside vim and in the terminal these lines do not seem to be picked up. Following this advice I also added the following line in my ~/.vimrc:
let g:syntastic_python_flake8_args='--ignore=E501'
But still E501 is shown as before (all other commands in my ~/.vimrc are correctly read by vim).
My flake8 --version returns 4.0.1 (mccabe: 0.6.1, pycodestyle: 2.8.0, pyflakes: 2.4.0) CPython 3.7.10 on Linux and flake8 --version in the terminal returns the following lines:

from the flake8 4.x changelog:
Due to constant confusion by users, user-level Flake8 configuration files are no longer supported. Files will not be searched for in the user’s home directory (e.g., ~/.flake8) nor in the XDG config directory (e.g., ~/.config/flake8)
you can of course use --config ~/.config/flake8 if you need to explicitly restore the previous behaviour
