Uppy Companion Problems with Nginx SSL Forward to 3020

Hey guys,

I just installed Uppy on a cloud server by Scaleway but I have a problem.
It worked but I needed SSL so I installed Nginx with letsencrypt so I installed it.

Now I need to forward Nginx to load Companion on port 3020 but it won’t work. Nginx is showing me: Nginx Error: The page you are looking for is temporarily unavailable. Please try again later.

I tried

location / {
    proxy_pass http://127.0.0.1:3020;
}

When I start companion it shows its running on 0.0.0.0:3020 (Is that weird or normal?) so I also tried

location / {
    proxy_pass http://0.0.0.0:3020;
}

And I tried

location / {
    proxy_pass http://localhost:3020;
}

But nothing seems to work. I’m probably missing something else in the config file. It would be great if somebody can point me the error.

The whole Nginx config file is as follows:

    server {
    if ($host = companion.mywebsite.com) {
        return 301 https://$host$request_uri;
    } # managed by Certbot


        listen       80 default_server;
        listen       [::]:80 default_server;
        server_name  companion.mywebsite.com;
    return 404; # managed by Certbot


}}

I managed to fix it. I feel so stupid right now. It was a permission error. Fixed by this command: setsebool -P httpd_can_network_connect 1
