How to setup htpps nginx+zabbix in docker?

Question

Nginx

Hello, there is a deployed zabbix in the docker using Nginx, everything works via http. Next, I created self-signed certificates via openssl -> ssl.key, ssl.crt, dhparam.pem Threw
them in /etc/ssl/nginxas described in the documentation https://www.zabbix.com/documentation/current/ru/ma...
Port 443 for docker thrown:

sudo lsof -i -P -n  | grep docker
[sudo] password for user:
docker-pr 11030            root    4u  IPv6  77784      0t0  TCP *:10051 (LISTEN)
docker-pr 11042            root    4u  IPv6  77811      0t0  TCP *:443 (LISTEN)
docker-pr 11054            root    4u  IPv6  77838      0t0  TCP *:80 (LISTEN)

The following configs are stored in /etc/zabbix/
nginx_ssl.conf config

nginx -tindicates that the server is down

nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful

but in the end, when I connect (I prescribe the server address), I get

Хмм. Нам не удаётся найти этот сайт. ы не можем подключиться к серверу zabbix.
Если этот адрес корректен, вы можете попробовать выполнить следующие действия:
    Повторить попытку позже.
    Проверить своё соединение с сетью.
    Если вы соединились с Интернетом, но защищены межсетевым экраном, проверьте, что Firefox разрешен доступ в Интернет.

I have ufw as a firewall on ubuntu, access to ports 443, 80, 10051 is open.

Answer 1

maybe I missed something, but IMHO nginx_ssl.conf is not connected.
Usually it should be put into the conf.d directory.
Or, to test, just add ssl config to the end of nginx.conf
