@ilovelnmp I'm assuming you are using Elasticsearch 8 with elasticsearch-php 8. The cURL erro 77 is CURLE_SSL_CACERT_BADFILE and its related with SSL certificate. I see you are using the .p12 file format for the certificate. Can you try to convert it in .crt format as suggested in the documentation? If you have openssl installed you can use the following command:

openssl pkcs12 -in filename.p12 -clcerts -nokeys -out filename.crt

where the input is filename.p12 (in your case http.p12) and the output is filename.crt. Let me know if this fix the issue, thanks!
