I’ve tried different methods to fix it, such as disabling all plugins, clear Cloudflare cache or clear browser cookies with no success.
Also try:
– switching to the unedited default Theme (Twenty Sixteen, etc.) for a moment using the WP dashboard to rule out any theme-specific issue (theme functions can interfere like plugins). If you don’t have access to your admin area, use FTP , or your web-host’s cPanel or whatever file management application your host provides (no Dashboard access required). Navigate to /wp-content/themes/ and switch to the default theme by renaming your current theme’s folder by adding “-old” to the end of the folder name. Alternately, you can remove other themes except the default theme. That will force your site to use it.
– If all the above steps do not resolve the issue, then try MANUALLY updating. Download a fresh copy of the WordPress .zip file to your computer, unzip it, and use that to copy up all files and folders EXCEPT the wp-config.php file and the /wp-content/ directory. You may need to delete the old wp-admin and wp-includes folders and files on your server before uploading the new ones. Read the Manual Update directions first.
– Backup: If you haven’t already done, always backup everything (including your database) before doing any actions, just in case something really goes wrong.
Thanks for your answer.
1 Switching to the default theme (2016) didn’t work.
2 A manual upgrade didn’t fix it neither
3 The only thing that worked was to downgrade to 4.3.2 (and that’s not a real solution)
It seems clear there’s a conflict between Mod_Security and WP 4.4.1. If Mod_Security is on, WP fails at login (404 error), but if it is off, WP works as expected.

yes. So the best is to contact the hosting provider.
