"app n8n cloud refused to connect" error. Not worked for 30 Hrs?

Hi All, (still unable to run webhook workflows, 2 days now)

I been building/running a workflow via webhooks for a while now, airtable and html user interaction and as of yesterday I haven’t been able to get past the “refused to connect” message that pops up on the browser window after submitting the last user html input.

It’s been fine until yesterday and not had this problem over the past few months. I’ve also been through all the forums and tips, no luck.

There are no errors in the workflow.

It may be something to do with the version update i did?

I’ve run my other workflows that use slack and chat and they run fine? So maybe something to do with webhooks ?

Anyone else having the refused to connect issue or worked out how to fix?

n8n Version - 1.103.2
n8n cloud
Windows 10

Appreciate anyone’s help as I was hoping to get my MVP out to user testers today.

Thanks

yeah that “refused to connect” on webhooks usually comes down to a few things - first check if your webhook URL itself is still valid (sometimes they change after updates), then make sure the HTTP Response node is actually returning something (even a simple 200 status). also worth checking your workflow execution logs to see if its timing out or hitting a size limit on the response. if those look good, try testing the webhook directly with a curl command or postman to isolate whether its an n8n issue or something on your end - lmk what you find
