Hi ! I just copy/past a previous issue because i face the exact same

I am trying to connect to salesforce sandbox via OAuth Connection

## I’m trying to connect my **Salesforce Sandbox** to n8n Cloud using the built-in Salesforce OAuth2 credential.

- n8n version: 1.117.0 (Cloud)

- Auth type: OAuth2

**What I tried:**

1. Created a Connected App in Salesforce with OAuth enabled.

2. In n8n, set up a new Salesforce credential → selected **Environment Type = Sandbox**.

3. When I click **Connect my account** , it always redirects me to `login.salesforce.com` (production login), not `test.salesforce.com` or my sandbox domain.

Since the redirect always goes to `login.salesforce.com`, my sandbox user credentials are rejected with _incorrect email/password_, they only work on the sandbox domain.

What am I missing ? Need urgent help with this.

I found that selecting “Use Custom Domain” and entering the sandbox name was a successful workaround when prompted with the [login.salesforce.com](http://login.salesforce.com/) authentication screen

@Arnaud_Desile Did the “Use Custom Domain” solution work?
