Hi i’m new to n8n and automation and i’m running a self hosted instance of n8n on render, and i can’t seem to authenticate my google calendar i get a “Error:OAuth callback failed because of insufficient permissions”. But i also have a copy of n8n running locally on my pc and that works fine. Can anyone assist?

You have it set to localhost, normally this isn’t a good idea for oauth2 as it is often not accepted by the application either. So probably something to do with that.

So you need to set the env variable to change the URL. you should have done this on your other instance as well

I am brand new to N8N. I have an N8N instance set up on Render using the Docker image. Can someone explain how to set the environment variable to change the URL. I am getting the following when trying to connect to Gmail.
