Hi Sierra!

I’ve hit a snag while preparing to do a HTTPS POST.

I’m getting a **KHTTP\_ERROR 5** , which according to the manual means “ **HTTP connection error due to internal trouble** ”.

What steps would you try next to get past this hurdle?

Thanks in advance for your help!

Cheers

Hi timroadley,

You are configuring http\_version= 2 (HTTP 1.1 over TLS (HTTPS) in your log file.  
To perform HTTPS TLS connection to [api.sandbox.ewaypayments.com](http://api.sandbox.ewaypayments.com) server, you need to configure TLS version and store CA, Client certificate, client key, consistent clock to module. These certificates, keys are matched with [api.sandbox.ewaypayments.com](http://api.sandbox.ewaypayments.com) server.

I can start HTTPS TLS1.2 successfully with an internal server at my side.  
Please find the log file for your reference. [PROTOCOM\_TLS1.2HTTP.txt](https://forum.sierrawireless.com/uploads/short-url/qzlvt3f8Q7i4kwcBi8EHSr6hNt4.txt) (10.9 KB)

Ah excellent. I’ve solved the problems with my https certificate so it loads properly before this call.

I’m getting a different error on a different command so will handle that in a new thread.

Cheers
