I can't log in after a period of inactivity

Heya,

The website should be working without a need for a restart.|

When that happens again, check your nginx and pm2 logs. Also, check the logs of the Droplet. It’s possible the Droplet runs out of memory and kills the process keeping the website up.

Hi,

First, look at your PM2 configuration, use pm2 show index and ensure it’s set to restart on failures (–restart-delay can help prevent rapid restarts).

Also, check if the --watch flag is enabled, as it can help restart the process when files change. If your server goes down due to inactivity, you might want to check if there’s any resource throttling happening on your droplet (use htop or free -m to monitor RAM usage). For Express, you could try keeping a persistent connection by sending periodic keep-alive requests, or use pm2 keep-alive settings.

If Nginx is involved, make sure your proxy settings aren’t timing out connections (proxy_read_timeout and proxy_connect_timeout values can be increased). If the issue persists, look at syslog or pm2 logs to find what’s actually killing the process.
