I have an self-hosted n8n setup and i try to connect with Google Sheets api. I have a set-up working https domain but it keeps returning 400 error when trying to log in into google cloud project inside creating n8n credentials. What could be the problem cause i ran out of ideas to solve this.

Hi,
I’ve had similar issue running it on my home server, but i think it was because of how i setup a reverse proxy to handle ssl and a ‘fake domain’ (i.e. https://n8n.local)
If you are running n8n in a similar setup you can try to add the credentials from the n8n host..
