Hi HubSpot Team,

We are experiencing an intermittent connection reset error when calling HubSpot APIs. Below is a sample error log. This issue is also occurring with other HubSpot APIs. We would like to understand the possible reasons behind this frequent occurrence in HubSpot. Thanks

Hi @mochi15,

Here are a few common causes and suggestions to help you troubleshoot:

  1. Temporary drops or fluctuations in your network connection can cause resets. Try running your integration from a different network or location to rule this out.
  2. If you’re making a high number of requests in a short period, HubSpot may throttle the connection. Check your API usage and consider adding retry logic with exponential backoff to handle rate limits gracefully.
  3. Some company firewalls or proxies may interrupt long-running or frequent API calls. Make sure your network allows outbound connections to ‎`api.hubapi.com` and isn’t terminating sessions early.
  4. Outdated or mismatched SSL/TLS settings can sometimes cause connection resets. Ensure your Java environment and libraries are up to date.
  5. Occasionally, the issue might be on HubSpot’s end. You can check status.hubspot.com for any ongoing incidents.

If you’ve checked these and the problem persists, try capturing more detailed logs (including request and response headers) and reach out to HubSpot Support with those details. They may be able to spot something specific in your account or region.
