I am calling an Apex Remote Action which performs an HTTP callout to an external service in AWS. Work fine in my Partner DE Org. Pushed the code to the customer's Sandbox and ran into the error.
Has any of you hardened Skuid-ers run into this sort of problem in the past?
After a quick google-bing, I ran across this KB:
** After the Summer '15 release, Apex callouts, Workflow outbound messaging, Delegated Authentication, and other HTTPS callouts will support TLS (Transport Layer Security) 1.1, TLS 1.2, and Server Name Indication (SNI). Customers' remote endpoints will have to be configured to support this update. **
