I have the latest version of n8n running in a docker container on localhost:5678
I have used this OAuth Redirect URL in the Google Auth: http://localhost:5678/rest/oauth2-credential/callback

What is the error message (if any)?

This site can’t be reached

localhost refused to connect.

Try:

  • Checking the connection
  • Checking the proxy and the firewall

ERR_CONNECTION_REFUSED

Hi, how do I set up allowed domains? I am deploying n8n in a local server.

Hi, it’s one of the options to configure when you setup oauth on google. similar location where you enter your oauth callback.

Hi, do you mean Authorized redirect URIs?I have put http://localhost:5678/rest/oauth2-credential/callback in to Authorized redirect URIs. Also, I gave n8n a domain name using the cpolar service. I can access the n8n service locally via both localhost:5678 and this domain. I saw that someone said it was a webhook issue, and I want to try to replace the OAuth Redirect URL in n8n with the domain name, how do I do that?
