Failed to fetch available update data

On a local Drupal 10 installation on WampServer64 (wamp64) I get the following error messages when checking the update status for the core and contrib projects:

Failed to fetch available update data

Failed to get available update data for 2 projects

Check PHP OpenSSL Requirements

The cause for this error message is the same as described in a previous article, but the message is less explicit:

https://drupaldope.com/wamp-windows-apache-mariadb-php/xampp-or-wampserver-local-drupal-installation-curl-error-60-ssl

The cure is the same, find your PHP installations, usually located in c:/wamp64/bin/php

in the files php.ini and phpForApache.ini , find the lines containing curl.cainfo= and openssl.cafile=  and make these sections look like this:

[curl]
; A default value for the CURLOPT_CAINFO option. This is required to be an
; absolute path.
curl.cainfo=C:\wamp64\keys\cacert.pem

[openssl]
; The location of a Certificate Authority (CA) file on the local filesystem
; to use when verifying the identity of SSL/TLS peers. Most users should
; not specify a value for this directive as PHP will attempt to use the
; OS-managed cert stores in its absence. If specified, this value may still
; be overridden on a per-stream basis via the "cafile" SSL stream context
; option.
openssl.cafile=C:\wamp64\keys\cacert.pem
