I'm getting an error on an API call when I use http_req(), but when I send the same payload using Postman, it works fine.

This seems to be an intermittent problem when calling the API from my IBM i. But it succeeds 100% of the time when called from Postman. Any help understanding the error would be greatly appreciated.

It basically means it doesn't understand the form of SSL (TLS) encryption that the remote server is sending.

Possibly you need to update HTTPAPI, or your operating system. Or perhaps the SSL/TLS support in the OS is misconfigured.

I am also facing Same issue. Could you please let me know what version of HTTPAPI should i upgrade to to fix this issue?

By Updating the HTTPAPI did the issue resolved for you or some other troubleshooting also needs to be done?

What version of TLS is being required?

What version of TLS is available in your copy of the operating system?

What ciphers are requested?

What ciphers are in your version of the operating system?

I can't help you if you provide no information.
