Workflow Activation Error — Too Many Requests (429)

Questions
1

I am experiencing an issue when attempting to activate a workflow in my n8n instance. The error message displayed is:

Workflow could not be activated:
Too Many Requests: retry after 1

🛠 Details:

  • n8n Version: 1.104.1
  • Hosting Environment: [self‑hosted / n8n.cloud / AWS / DigitalOcean / etc.]
  • Trigger Method: Activation via UI (activate toggle after editing)
  • Frequency: Occurs every time I attempt to activate this workflow
  • Workflow Contents: Telegram Trigger, HTTP Requests (OpenAI + Leonardo + PDFMonkey), multiple nodes including Set, If, Function, Google Drive, EmailSend, etc.
  • Errors or Warnings:
    • Error popup shown in UI (see meeting screenshot)
    • “Too Many Requests: retry after 1” again on activation attempt

📸 Screenshot Notes:

  • On the canvas, you can see multiple node chains with Telegram triggers.
  • At the bottom right, the message:

Workflow could not be activated: Too Many Requests: retry after 1

  • At the bottom left, the run button shows the context:
    Execute workflow from Wait for Selection (Telegram Trigger)

🧪 Troubleshooting Steps Already Taken:

  • Waited briefly and retried activation — same result
  • Verified no duplicate Telegram trigger is active (Telegram webhook counts are correct)
  • Confirmed only one active Telegram trigger exists in this workflow
  • Reviewed log files – no additional details beyond the 429 message
  • No concurrent workflow activations elsewhere

🚩 Additional Context:

  • I have seen on community forums that activating multiple workflows with Telegram triggers can result in rate-limiting.
  • I also run no other n8n instances triggering the same bot token.
  • It appears the system isn’t allowing activation despite UI showing only one workflow using this token.
