Hi @Ruriko, there’s currently no way to tell a specific credential like Google OAuth2 to use a proxy server but if you run n8n with docker, you could configure it to use a proxy.
Could you share a bit more context around why you want to use a specific proxy for a credential? Maybe then the community can suggest other workarounds and suggestions
The only reason why I want to use proxy cause some services are region blocked. I was thinking maybe using HTTP Request node since it has the ability to use proxy but I’m not sure if it’ll using the proxy for authentication login. Is there some way to test it if it’s using proxy when it login to account?
