Backendless Version (3.x / 5.x, Online / Managed / Pro )

Client SDK (REST / Android / Objective-C / Swift / JS )

REST

Application ID

86DF97EF-A838-427E-A069-5F4DC2B95285

Expected Behavior

Please describe the expected behavior of the issue, starting from the first action.

  1. REST API call succeeds without TLS issues

Actual Behavior

Please provide a description of what actually happens, working from the same starting point.

Be descriptive: “it doesn’t work” does not describe what the behavior actually is – instead, say “the request returns a 400 error with message XXX”. Copy and paste your logs, and include any URLs.

  1. We get an SSL error from Zapier sporadically when we try to call our REST API service(see attached images)

Reproducible Test Case

Zapier support gave me a link to this tool to show the issue: TLS Checker - Instant Results | CDN77.com

Hi Christopher,

I opened an internal ticket for our devops team to check the issue (BKNDLSS-31452).
