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/posts— FAILS - 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:
- Has anyone else experienced Bluehost blocking n8n Cloud?
- Can n8n support confirm requests are leaving their servers?
- Is there a list of n8n Cloud IPs I can ask Bluehost to whitelist?
- Any workarounds?
Note to n8n staff: I can provide my workspace URL via DM if needed.
Thanks for any help!
