Hi everyone !!!
I’m using the EC800M-CN
When I try to send http request by using example_httpclient, this errors. And I don’t know what happen because I was check log all ql_http_client_setop(…), it notifies that all success. Even I comment the function set SSL, this still error.
May I can solve this problem?
Hi @Haaa
From the screenshot, it can be seen that the SSL certificate is not found. Please confirm whether the server needs to verify the certificate. If so, please upload the correct SSL certificate. If not, you can choose the no-certificate verification mode to try.
You can follow below steps for HTTPS post with the added headers.
