Using Eclipse Kepler, I've followed these instructions and tried all 3 available IDE versions (31, 30, 29) but cannot successfully connect to my org's production environment or a developer environment spun off production. I have been able to connect to a new developer sandbox I've just generated to see if that works, so not sure what the issue is.

Steps I've followed are:

  1. Install JDK 7 Install Eclipse Kepler 'IDE for Java Developers'
  2. In Eclipse installed IDE v31
  3. Open Perspective --> Other --> Force.com
  4. File --> New --> Force.com project
  5. Entered Username, password, security token Selected Production/Developer Edition environment
  6. Clicked next
  7. At this point I get "Unable to connect to hostname 'www.salesforce.com': Invalid username, password, security token; or user locked out."

I'm positive I've got the correct username, pw and token, and I've also tried the above steps with a developer org of the production org (for environment tried both sandbox and Other - test.salesforce.com without success). I've tried all of this with v31, v30 and v29. I've also tried Environment Other - ap1.salesforce.com (the server our SF instance sits on) with the same result.

Any ideas what I'm doing wrong?

  • Chances are you're trying to connect to salesforce behind your office firewall. You may need to configure proxy setting in eclipse so that you can access salesforce.

Some basic validation it brings to my mind – check if you didn't go through this already!

  • See if your account is really locked out

  • Is your user account profile has API enabled (hope you might be using System Administrator profile – in case of that this is also enabled by default)

  • Try including your IP range in Security Control -> Network Access (it will help if IP range was enforced)

  • 1
    interesting might also be that if your ip is trusted/whitelisted I don't believe you still need the security token. Commented Mar 19, 2015 at 10:59
  • I also the same issue.I able to get link with production but no luck at all in sandbox.I am system administrator.my ip range is included and when I check login history no data att all.I wondering what else I should check as I successfully connect to Production but fail in sandbox.

  • @unidha Recently there are some certificate related issues, connected with our office admin admin team they installed some certificate and resolved. if you are connecting from office laptop/desktop and using office network check with office IT admin/network team Commented Jul 13, 2016 at 5:02
