The issue has been resolved. It was due to a misconfiguration on our TLS endpoint that made it incompatible with Apex Callouts (and some Java versions). I've confirmed Apex Callouts are once again working.

It sounds like your SSL Library doesn't support 2048-bit DH parameters. Take a look at the BouncyCastle SSL Library as an alternative to what you're using. https://www.bouncycastle.org/latest_releases.html If you continue to have problems after changing to BouncyCastle, please email us at support at goinstant.com so we can do a more in-depth debug of your problems.

  • In salesforce I am not able to check what ssl library they are using and what features are available in the Library they are using. But one thing I can say is I have done thousands of Callouts with various external systems and never seen this problem except you. I am not even find any expert who can explain how to solve this. So please let me know how can I call your system via Rest Api from salesforce. You are part of salesforce so I assume you are accessible from salesforce . Please help me with this problem. Thanks. – ashishcloud May 22 '14 at 05:51
  • Sorry, Support misunderstood that you were using Apex; I'm digging into the solution now. – stash May 22 '14 at 16:54
  • Turns out we accidentally disabled ECDHE support on our TLS terminator; we should have this fixed shortly. Your patience is appreciated and sorry once again for the confusion. – stash May 22 '14 at 17:57
