Issue

An attempt to send POST request via KPSN API from a Windows client.:

curl --cert C:\\Users\\user_A\\Desktop\\kpsn_api

kpsn_api_crt.pem --key C:\\Users\\user_A\\Desktop\\kpsn_api

kpsn_api_key.pem -k -X POST -d "{\\"action

": \\"check_url\\",\\"data

": {\\"urls

": [\\"website1.com

"]}}" https://10.90.116.27:80/api/

Fails with the following error:

curl: (58) schannel: Failed to import cert file C:\\Users\\user_A\\Desktop\\kpsn_api

kpsn_api_crt.pem, last error is 0x80092002

There is no such issue when using curl on a Linux client.

Cause

The used version of curl.exe on Windows is not configured to work with OpenSSL.

Solution

Use other tools to send requests, e.g Insomnia or curl from Git for Windows.
