Search Pro is not working on mobile phones

Hi Neto,

Thank you for the details!

When I am logged out I get the same error message on both desktop and mobile. The error response reveals this message from your server: https://i.imgur.com/Ohxkc2J.png
This means, that a firewall/server policy is blocking the requests to the wordpress ajax handler. If you use any firewall/fence plugins, check the firewall configuration. It is more likely coming from the actual server or CDN, you may have to check the firewall on that end as well.
There is a ray ID you can refer to for a block to filter further requests: RID: GCUQZ346G2S8KVREXVD0BWLC

Well, that is a tough question, because it highly depends on what exactly triggers the block.
I assume there is some sort of an interface, where you can look up past blocks by their ray IDs. Finding the block by that ray ID should clarify what exactly triggered the firewall to block the whole request. Then it should offer a way to make an exception for that request type.

Usually it’s something to do with the request body – something in the POST variable, maybe an argument it resembles a threat in the heuristics database.

Try maybe something like:

admin-ajax.php
/wp-admin/admin-ajax.php
