Nginx deploy shows another account

Troubleshooting
1

Hi friends, i deployed Mattermost via docker container in a shared centos server

but i have a problem, Im the system admin, and i open Mattermost in my computer, but if another user open Mattermost in another computer, when I reload the webapp, i see the other user info session, not my account as system admin

The next is my nginx conf file (subdomain.mydomain.com):

upstream mattermostbackend {
   server 127.0.0.1:8065; #8088
   keepalive 32;
}
proxy_cache_path /var/cache/nginx/$domain levels=1:2 keys_zone=mattermost_cache:10m max_size=3g inactive=120m use_temp_path=off;

    listen	serverip:443 ssl;
