ssl_error(415): (GSKit) Peer not recognized or badly formatted message received.

[kdanforth]

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.
