net::ERR_CONNECTION_REFUSED After resizing droplet

Posted on January 4, 2024

Asked by Tarik Neaj

Yesterday we decided to resize our droplet. Before that, everything was running fine. Our Node/Express server was up, and we could connect to it.

After resizing it. We could no longer fetch from the server, even though the application is 100% running, I’ve checked many times, via pm2. Logs are being printed out constantly.

I’ve read countless threads and tried countless solutions, none that worked so far. Port seems fine. Firewalls are disabled.

The 2 errors we are getting are net::ERR_CONNECTION_REFUSED and TypeError: Failed to fetch.

The application runs fine on localhost, just not on the droplet. Would appreciate any help. If there’s any further information needed please let me know.

Edit: Not sure how relevant, but I ran “service nginx status” and got the following:

● nginx.service - A high performance web server and a reverse proxy server Loaded: loaded (/lib/systemd/system/nginx.service; enabled; vendor preset: enabled) Active: failed (Result: exit-code) since Wed 2024-01-03 21:00:38 UTC; 13h ago Docs: man:nginx(8) Process: 903 ExecStartPre=/usr/sbin/nginx -t -q -g daemon on; master_process on; (code=exited, status=1/FAILURE)

Hi there,

As far as I can tell from the output, the primary issue seems to be with Nginx, as indicated by the failed status in your service nginx status command.

The logs suggest problems with accessing the log files (/var/log/nginx/error.log and /var/log/nginx/access.log). This could be due to permission issues or missing directories/files.

First, ensure that the /var/log/nginx/ directory exists and has the correct permissions. You can recreate it and set appropriate permissions using commands like sudo mkdir -p /var/log/nginx/ and sudo chown -R www-data:www-data /var/log/nginx/.
After fixing the log directory issue, try restarting Nginx with sudo systemctl restart nginx and try again.

Let me know how it goes!

Best,

Bobby
