Did not test a new update again yet. Deactivating all plugins did not resolve the issue.Emptying cache either.All requirements on the server are up to date.Bit annoying and uncommon for a WordPress update;) * Thread Starter [Guillermo](https://wordpress.org/support/users/guillermo77/) * (@guillermo77) * [2 years, 6 months ago](https://wordpress.org/support/topic/wordpress-6-4-error-api-rest-http_request_failed-curl-error-28/#post-17190133) * (@rezatar) It was solved yesterday without doing anything * I think no is jetpack, maybe WP 6.4 * Try agai**n, **give it a couple of days * [Gizmo](https://wordpress.org/support/users/rezatar/) * (@rezatar) * [2 years, 6 months ago](https://wordpress.org/support/topic/wordpress-6-4-error-api-rest-http_request_failed-curl-error-28/#post-17191391) * Yes, thank you.
