Question docker php-fpm 502 Bad Gateway

[zippo]

step:
1. setup new SubDomain on plesk

2. pull docker image from private repository and run

3. set new Docker Proxy Rule for this subdomain

4. When I go to this url subdomain I got 502 Bad Gateway (nginx)


What I'm doing wrong?
Are there any additional configurations?


my docker image:
