Issue with SSL/TLS Connection to ERP API - ERR_OSSL_UNSUPPORTED

What are you trying to achieve?

I’m trying to integrate my ERP system, with Make.com to automate data retrieval for our sales dashboard. Specifically, I’m calling their API to fetch and sum invoice data from the current month.

However, when I set up the HTTP module in Make.com, I receive the following error: ERR_OSSL_UNSUPPORTED: error:1E08010C:DECODER routines::unsupported.

The same API request works fine in Postman, which suggests there might be an SSL/TLS compatibility issue between Make.com and the MetaKocka (ERP system) API.

  • Has anyone encountered this issue before with SSL/TLS on Make.com?
  • What should I ask my ERP provider to check or update on their server to resolve this?
  • Any suggestions on how to troubleshoot or bypass this issue?

Steps taken so far

Check with Postman if there is any other problems. Also I unchecked “Reject connections that are using unverified (self-signed) certificates” for test purposes. Tried different calls, but the error is still the same.
