SSL не работает с nginx и docker-контейнером

У меня проблемы с установкой сертификата SSL на нестандартные порты в моем веб-приложении.

У меня есть проксирование nginx для предоставления трафика моему докер-контейнеру. Я установил сертификат SSL, и он отлично работает со стандартными портами (80 и 443), но не работает с такими портами, как 8881 и 59874.

Это моя конфигурация Nginx:

server {
    listen 80;
    listen [::]:80;
    server_name smisl.net;
    return 301 https://$host$request_uri;
}

server {
    listen 443 ssl http2;

    ssl_certificate /etc/ssl/smisl/smisl.crt;
    ssl_certificate_key /etc/ssl/smisl/www.smisl.net.key;

    server_name smisl.net;

    client_max_body_size 6m;

    if ($http_x_forwarded_proto = 'http'){
        return 301 https://$server_name;
    }   


    location / {
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header Host $host;
        proxy_set_header X-NginX-Proxy true;
        proxy_set_header Upgrade $http_upgrade;        
        proxy_set_header Connection "upgrade";
        proxy_pass http://127.0.0.1:60001/;
        proxy_redirect http://127.0.0.1:60001/ https://$server_name/;
    }
}

А это мой конфиг докера:
