There is one server where php application is hosted under IIS. I have installed the ".pfx" file on the server and associated it with IIS application.
When developers connects to this application , they are getting below error.
This certificate is valid (not expired) and issued by an authorized org.
"cURL error 60: SSL certificate problem: self signed certificate in certificate chain"
Don't know why they are getting errors. I don't want to turn off the "CURLOPT_SSL_VERIFYPEER " option.
What I have found , when an application connects to the server, it accepts that request. But then this request makes another API guzzle call to get some data. AT this stage , the application is throwing an error.
Why is it causing this issue ? and How to fix this error?
