About the error you encountered:
“SSL certificate problem: unable to get local issuer certificate”
This error usually indicates that the server cannot properly verify the SSL certificate chain. Even if the SSL appears valid in the browser, the server may still be missing the intermediate or root certificate, or the local CA bundle used by PHP/cURL may be outdated.
SSL Certificate Problem: Unable to Get Local Issuer Certificate: Causes, Fixes, and Prevention
Common causes include:
- The server does not provide the full SSL certificate chain (missing intermediate certificates).
- The CA certificates on the server are outdated.
- The PHP/cURL configuration cannot locate the CA bundle used for SSL verification.
What you can check
Please try the following steps:
-
Verify your SSL installation
- Ensure the SSL certificate is installed with the full chain (including intermediate certificates).
-
Update the CA certificates on the server
- Your hosting provider may need to update the server’s CA bundle.
-
Check PHP cURL configuration
- Ensure
curl.cainfo or openssl.cafile is correctly set in your php.ini.
- Some servers require pointing PHP to a CA bundle (e.g.,
cacert.pem).
-
Ask your hosting provider
- Since this is a server-level SSL validation issue, the hosting support team may need to verify the SSL chain and PHP configuration.
In most cases, once the server SSL chain or CA bundle is fixed, the token generation works normally.
Best regards
