WordPress Media Upload Fails - "Connection Aborted" - Bluehost Blocking n8n Cloud?

Hi everyone,

I have a workflow that uploads images to WordPress Media via the REST API. It worked perfectly for weeks, then suddenly stopped — I haven’t changed anything.

The error:

  • “The connection was aborted, perhaps the server is offline”
  • Timeout after 10-30 seconds (same result either way)
  • Also seeing: Converting circular structure to JSON → property 'parser' → property 'socket' closes the circle

What I’ve tested:

  • Simple GET request from n8n to https://mysite.com/wp-json/wp/v2/postsFAILS
  • Same URL in my browser — WORKS instantly
  • REST API is enabled and responding
  • Created new Application Password
  • Disabled all WordPress security plugins
  • Not using Cloudflare

My setup:

  • n8n Cloud (not self-hosted)
  • WordPress hosted on Bluehost
  • HTTP Request node uploading binary image data

Bluehost response: I’ve been working with Bluehost support for a week. They claim nothing is wrong on their end and point to my n8n workflow as the problem. But a simple GET request with no authentication also fails, so it’s not my workflow.

My theory: Bluehost is blocking n8n Cloud’s IP addresses at the firewall level. The connection hangs and times out rather than being rejected — suggesting packets are being silently dropped.

Questions:

  1. Has anyone else experienced Bluehost blocking n8n Cloud?
  2. Can n8n support confirm requests are leaving their servers?
  3. Is there a list of n8n Cloud IPs I can ask Bluehost to whitelist?
  4. Any workarounds?

Note to n8n staff: I can provide my workspace URL via DM if needed.

Thanks for any help!

Here is the official list of IPs for the n8n Cloud service:

To get in touch with n8n support, I’d recommend to contact [email protected]

What you can try until you receive a reply from them:

Spin up a locally hosted n8n instance and see if it works, which would be another indicator.
Send me your website url via DM and I will try from my local and cloud instances aswell.

did you get anything figured out? i have been on with hostgator support for last three days
