[Self Hosting] Problem With My OATH Redirect URL

I keep getting an error message (maybe because it’s a localhost?) in n8n while trying to connect to my Google Calendar.

For context, I am hosting using Render. I’m kind of new to all of these and may have skipped some steps, if you have any questions please ask. Thank you!

Information on your n8n setup

  • n8n version: 1.99.1
  • Database (default: SQLite):
  • n8n EXECUTIONS_PROCESS setting (default: own, main):
  • Running n8n via (Docker, npm, n8n cloud, desktop app): Render
  • Operating system: Windows

Hey @Mori_Arvian hope all is well, welcome to the community.

Exactly because it’s a localhost, please see the following doc for the solution

Hi! Thank you @jabbson! I have tried changing the webhook URL based on Render’s tutorial, but it still shows up as localhost in my n8n workflow.

Did you re-deploy after setting that?

Yes, I did here (is that the correct one?)

It probably is, never used render. Have you tried to re-add the node after you restarted the service?

I did and it’s still the same URL in the new Gmail

What about that other option - deploy latest reference, what does that do?

Note: only make changes it if you know what they are, like I said I never used render, so you must make sure you understand the options before you click on them. I bear no responsibility.

Welp, I tried running it and it wipes my data hahaha, it’s fine though, I haven’t gotten far with it. Seems like I haven’t input the storage for my data yet, and I might need to work on that first.

Please do let us know after you are done, doing so will help then next person who has the same question as you did.

Yes, investing in persistent storage (at least some) would be great, but you can also export and re-import both your workflows and credentials, if you have set some up already.


Hi! So I created it again from scratch, now I have a new OATH Redirect URL, but it comes with another problem haha, now it shows this error:

In google cloud console, you have to go and configure this new url so Google knows which n8n url to trust.

So, this is all because I was doing it wrong. If you want to try doing n8n using Render. Try doing it through this tutorial and there should be no problem in deploying anything.
