WordPress. Solution “cURL error 60: SSL certificate problem: unable to get local issuer certificate”

Once on one of the sites I noticed in WordPress the menu “Tools” – “Site Health” the following errors:

Rest API issued an error

  Request to REST API failed due to error.
  Error: cURL error 60: SSL certificate problem: unable to get local issuer certificate

Your site could not perform a loopback request.

  Error: cURL error 60: SSL certificate problem: unable to get local issuer certificate

Jetpack also wrote that there is a problem with the connection to its server.

The reason was not specified by SSLCertificateChainFile in the Apache2 configuration, only the following were specified:
SSLCertificateFile /etc/letsencrypt/live/ixnfo.com/cert.pem
SSLCertificateKeyFile /etc/letsencrypt/live/ixnfo.com/privkey.pem

Therefore, I added:
SSLCertificateChainFile /etc/letsencrypt/live/ixnfo.com/chain.pem

And restarted Apache2:
sudo service apache2 restart

After this error disappeared.
