HTTP Call to HubSpot returns 403

Hi there,

I use n8n to automate some actions around HubSpot. Since last night, we receive an error 403 from HubSpot with a strange response, but the logs inside HubSpot say that it sent a 200 response.

I don’t have this issue with HubSpot built node in n8n, only with HTTP call custom nodes.

Did something change recently that could explain this?

The error starts like this:

403 - "Just a moment…Enable JavaScript and cookies to continue(function(){window._cf_chl_opt={cvId: ‘2’,cZone: "api.hubspot.com",cType: ‘managed’,cNounce: ‘50418’,cRay: ‘83fa09cc4d1e79d7’,

Information on your n8n setup

  • n8n version: 1.20.0
  • Database (default: SQLite): Postgres on Heroku
  • n8n EXECUTIONS_PROCESS setting (default: own, main): default
  • Running n8n via (Docker, npm, n8n cloud, desktop app): Heroku
  • Operating system:

Update :

It seems like there is a problem with some Heroku (that I use for the hosting of n8n) IP adresses that are banned by Cloudflare for an unknown reason.

Hey @romain_saillant,

That is good to know thanks for the update, I suspect people have been using Heroku to spam Cloudflare protected sites and that has triggered the IP ranges to be restricted.
