This error means PDF.co couldn’t complete the request due to a temporary connection issue.
Why It Happens
The connection between your platform (e.g., Zapier, Make, or direct API) and PDF.co was interrupted
Our servers may be experiencing a brief delay or heavy load
Your workflow timed out before PDF.co could respond
How to Fix It
Zapier
Use Zapier’s replay tool to retry the failed task
If the error continues, add a short delay step before retrying or insert a path to handle retries
Make.com
Add error handling to retry the step automatically
Use a “Sleep” module between retries to give PDF.co time to recover
Refer to Make’s retry documentation →
Direct API
Implement retry logic with exponential backoff (e.g., retry after 5s, 10s, 20s)
Monitor HTTP response codes and only retry for temporary timeouts
