STEP 1
Login to your server with your SSH credentials.
Using curl, enter the following command:
curl --insecure https://curl.se/ca/cacert.pem -o /etc/ssl/certs/ca-certificates.crtSTEP 2
Set the file permissions:
chmod 444 /etc/ssl/certs/ca-certificates.crtSTEP 3
Edit your php.ini file and add the below content at the end:
[curl]
curl.cainfo = /etc/ssl/certs/ca-certificates.crt
[openssl]
openssl.cafile = /etc/ssl/certs/ca-certificates.crtSTEP 4
Restart your webserver (in this example we use Apache):
systemctl restart httpdSTEP 5
Click on “Test These Settings” again, and now you should see:
SMTP connection was successful!
