Wordpress cURL error 60


I built a cluster with Rancher 2.4, install wordpress from rancher catalog with nfs storage class, listening to nodeport.
Everything was easy thanks to Rancher.
But I can’t install plugins and make updates inside wp-admin.
The Site Health Status shows the following error message:

Could not reach WordPress

Communicating with the WordPress servers is used to check for new versions, and to both install and update WordPress core, themes or plugins.

Error Your site is unable to reach WordPress.org at my public IP, and returned the error: cURL error 60: SSL: no alternative certificate subject name matches target host name ‘api.wordpress.org
