N8N Trigger Failing with Multiple Errors (Unauthorized, DNS, 503, 404, 403)

I’m hitting a critical issue with my n8n Softr trigger and I’m completely stuck.

I have a workflow using the n8n Softr trigger node, set to ‘On Create Record’.

The Problem

I’ve suddenly started getting a flood of errors from this one trigger, and they are all different. The errors include:

  • Unauthorized

  • Forbidden

  • Bad param

  • Service unavailable

  • The DNS server returned an error, perhaps the server is offline

  • The resource you are requesting could not be found

This is happening even when I am not actively creating any records in Softr. It seems to be triggering on its own and failing.

My Questions

Given the wide variety of errors (from DNS/network issues to authorization issues), I’m no longer sure this is a simple mistake on my end.

  1. Is anyone else seeing this? Could this be a temporary instability with the Softr API or the webhook service?

  2. Could this be a webhook issue? Is it possible a webhook is misconfigured, “stuck,” or repeatedly trying to call n8n with bad data, causing all these different failures?

  3. How can a DNS error and an “Unauthorized” error happen at the same time? This combination is the most confusing.

I’ve already double-checked my API keys, but the fact that I’m also getting 404s, 503s, and DNS errors suggests the problem is bigger than just bad credentials.

Any advice on how to troubleshoot a trigger that’s failing in so many different ways at once?
