I Hey everyone, I'm pretty new to Railway and N8N, and I'm running into an issue with Google OAuth.
Hoping someone can point me in the right direction.

I'm hosting N8N on Railway and trying to connect it to Google Sheets via OAuth.
When I try to authenticate via Google OAuth in N8N, I get a "403 error: access_denied"

I've tried every possible way to connect via YouTube, but it just won’t work.
While searching past posts, I found mentions of "custom domain" and other related stuff—but honestly, I have no idea what that means.

I really need some help here. If anyone can explain what I might be missing, I'd be super grateful.
I'm on Hobby Plan now.
