Salesforce Lightning - Login Failure In Staging

Question

I'm trying to login into my staging Salesforce lightning, by I get the following result:

INVALID_LOGIN: Invalid username, password, security token; or user locked out.

I use the 'jsForce' library version 2, with the right serverUrl, username and password+token combination.

Note that when I do exactly the same for my production Salesforce environment - I succeed.

Any suggestion to why there's a difference between staging and production.

Answer 1

https://test.salesforce.com versus https://login.salesforce.com. Even if you use the same password, the token may be different, or the password may have expired.

In setup, do you see anything in the user's login history? It's difficult to make educated guesses about these topics. Do you receive the same outcome when you use the SOAP API or OAuth2? Or maybe just basic SF Data Loader?

Maybe admin disabled logging in from generic addresses in Setup -> My Domain, requiring you to go to https://mydomain—mysandboxname.my.salesforce.com/...?

Maybe the admin had everyone use Single Sign-On, and you can't use your SF username and password anymore.

There may be IP addresses that are restricted or login hours that have been defined.
