Question

Mern stack droplet 502 Bad Gateway nginx/1.24.0 (Ubuntu)

Hi again, I spun up a new droplet and can’t get the app to appear. Please help as I’m at a loss, thanks!

Following is my error log.

This is my nginx config file



server {

        index index.html index.htm index.nginx-debian.html;

        server_name outdoors.rest www.outdoors.rest;



        location / {

                proxy_pass http://localhost:5050;

                proxy_http_version 1.1;

                proxy_set_header Upgrade $http_upgrade;

                proxy_set_header Connection 'upgrade';

                proxy_set_header Host $host;

                proxy_cache_bypass $http_upgrade

        }



         location /api {

            proxy_pass http://localhost:5050/api;

            proxy_http_version 1.1;

            proxy_set_header Upgrade $http_upgrade;

            proxy_set_header Connection 'upgrade';

            proxy_set_header Host $host;

            proxy_cache_bypass $http_upgrade;

    }

I think that the above happened because i took a snapshot and the droplet became corrupted. I spun up a new droplet and it’s working as before, so no need to answer, thanks!
