Impossible to upload bigger files in an Input field Files

[Sten]

Although my php.ini is upload_max_filesize = 1000M and I reloaded php fpm, I can't upload files above 2M. I looked at every post on this topic in the forum but could not solve the problem.
My error line is
error] 32540#32540: *1592 client intended to send too large body: 22592569 bytes, [...]  request: "POST /exploration/page/edit/?id=1114&InputfieldFileAjax=1
Thank you for any help.

That's an nginx error. You need to increase the client_max_body_size setting in nginx.conf.
