Recently we have been facing this connection reset issue in our droplets. Especially when the digitalocean server gives a lot of get/post request to other remote servers like firebase,telegram etc. We didn’t face this problem when we were in GCP. After coming to digitalocean, it ran fine for few days. But recently we are facing this issue? Can you please help? Note: We may give 4/5 requests per second to other remote servers.

Hi there,

This error usually means the remote service is closing the connection, not that the Droplet itself is broken. A Connection reset by peer happens when the other side (Firebase, Telegram, etc.) drops the TCP connection during the handshake or request.

A few things that could be going on here, and I’m not 100% sure which applies in your case:

  • You may be hitting rate limits or connection limits on the remote APIs. Even 4–5 requests per second can trigger short term throttling, especially if you open many new connections instead of reusing them.
  • If you are using requests without a session, you may be creating too many short lived TCP connections. Reusing a requests.Session() and enabling keep alive often helps.
  • Some APIs aggressively reset connections if TLS handshakes take too long or if traffic patterns change.

I would start by adding retries with backoff, reusing HTTP sessions, and checking OS limits (ulimit, open files, TCP settings). Also double check the rate limits and expected usage patterns for the APIs you’re calling.

Since this worked fine before and only started recently, it’s much more likely a traffic pattern or connection handling issue than a DigitalOcean networking problem.
