Php, session file access error session_start(): Failed to read session data: files?

Question

linux

Good evening,
I have: Centos 7, nginx, php-fpm72, percona, opensips 3.0 I'm trying
to install a web panel to opensips, I ran into a problem that the login and password do not match (I even checked everything from the hashes) Turning on the logs in php saw that there is a problem with access to the directory with sessions:

nginx runs as nginx user:
ps aux

nginx 10550 0.0 0.1 121416 3372 ? S 16:24 0:00 nginx: worker process

php-fpm from root
ps aux

root 10595 0.0 0.7 365568 13308 ? Ss Jan15 0:06 php-fpm: master process (/etc/opt/remi/php72/php-fpm.conf)

I try to put sessions in /var/nginx:
ls -la /var/nginx

drw-rw-rw-2 nginx nginx 6 Jan 16 16:52 session

I tried to give permissions 777 /var/nginx/session/ but to no avail, what am I missing?
