it is safe to whitelist and allow origin IP ?
or it is better to do somethig more specific?

i am not expert in security and i appraciate any help

Since it’s related to the WordPress, I’d suggest you to whitelist your origin host / server / hosting IP address by navigating to the Security → WAF → Tools → IP Access Rules with the action “allow” for your Website and try again.

It knows to happen due to the WordPress using HTTP/1.0 and empty user-agent, therefore while executing WP-Cron or some other related JSON/REST API request via plugin.
