Salesforce Sandbox OAuth2 connection failed

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: 1.110.1 (Cloud)

  • Auth type: OAuth2

  • Database: default

  • Execution process: default

What I tried:

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

  2. Added the n8n redirect URI in the Connected App.

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

  4. 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 authentication screen
