Connectivity & NTP Time Offset Issues

Resolved

(@vunderbar)

Howdy,

Fresh WP install on a shared GoDaddy hosting server with just WP Ghost and this plugin sofar. No page builders, themes, WooCommerce or website yet.

Issue 1 - Connectivity

On the Tools > Diagnostics tab, under the Connectivity section ... this issue (big ole red X):

Connecting to Wordfence servers (https) - OK

Connecting back to site

	wp_remote() test back to this server failed! Response was 404 Not Found

	This additonal info may help you diagnose the issue. The response headers we received were:

	HTTP/1.1 404 Not Found

	Date: Mon, 30 Mar 2026 20:37:10 GMT

	Server: Apache

	Upgrade: h2,h2c

	Connection: Upgrade, close

	Vary: Accept-Encoding

Transfer-Encoding: chunked

	Content-Type: text/html; charset=UTF-8

	<html lang="en-US"><head><title>404 Not Found</title></head><body><h1>Not Found</h1><p>The requested URL /wp-admin/admin-ajax.php?action=wordfence_testAjax was not found on this server.</p></body></html>

Connecting back to this site via IPv6 (Not required, this may not be an issue on some site.

	IPv6 DNS resolution failed

	Details

	This likely indicates that the server either does not support IPv6 or does not have an IPv6 address assigned or associated with the domain.

	Original error message: wp_remote_post() test back to this server failed! Response was: cURL error 6: Could not resolve host: (domain) www.sweetspark.co

I've since gone into the Advanced Scan Options and turned on the item for: Use only IPv4 to start scans.

Questions

1 - Is this a problem? Will this block or disable receiving WF updates?

-

2 - If so, how can this be fixed?

-


Issue 2 - NTP Time Offset

Have also noticed on the Diagnostics page under the Time Server section, the WF Network Time and Server Time are set at UTC.

The NTP Time Offset is "Blocked", and the NTP Status is “Disabled (failures exceeded limit)”.

TOTP Time Source is “Server Time”

WordPress Time Zone is correct at “UTC-7”.

I did a Reset of the NTP, but it's back to UTC time and Blocked again.

Questions

3 - Will this mismatch cause issues with accurate (local) times on the future site, eg - posts, ecommerce transactions, etc.?

-

4 - If so, how can the NTP Time Offset be “unblocked” so it can match the WP Time Zone?

-

General Questions

5 - For plugins, does it matter what order they're installed in? Eg. - Should the Security plugins, and then a Page / Site Builder be installed before WooCommerce, and then a Cache plugin?

-

6 - Setting this up for use with WooCommerce. Which Builder would work best or which would you recommend: Divi or Elementor?

Sorry, don’t know why the whole post above ended up in a box, or how to edit it. (Can the forum moderator please delete it for me?)

Hi @vunderbar

The connection error is likely due to the WP Ghost plugin and removing it should fix the error. Plugins like this that try to hide that a site is using WordPress can cause other plugins to malfunction including Wordfence. For example you may find the Wordfence scans won’t start or complete when using WP Ghost.

NTP is a protocol that allows for remote time synchronization if a server’s clock time is not correct. You can ask your hosting provider to check that for you. Wordfence Login Security uses this protocol to ensure that it has the most accurate time which is necessary for our TOTP based two-factor authentication feature to work correctly if you are going to use that.

It doesn’t matter what order you install plugins in WordPress.

We can only provide support for our plugin and general WordPress security advice so you can ask WooCommerce for advice on theme and page builder support for their plugin.

Hi Phil,

Sorry for the delayed reply.

According to WP Ghost, they say they’re compatible with Wordfence:
“Note! WP Ghost works with all plugins who run in the admin area.
Compatibility issues are unlikely, especially if you use the Safe Mode from WP Ghost.”
And as noted on this page:
“WP Ghost is compatible with the most popular plugins.”
https://wpghost.com/kb/wp-ghost-compatibility-plugins-list/ (Security Plugins section)

They also claim it’s complementary / good when used together with WF:
“WP Ghost is a hack-prevention security solution for your WordPress site.
Together with the WordFence plugin, it will boost your website security by stopping hacker bot attacks, spammers, and viruses and preventing data loss.”
https://wpghost.com/kb/wp-ghost-and-wordfence-security/

The WF scans have been able to run and complete without issue.

That being said, removed WP Ghost, reran a WF scan, checked Diagnostics and … all is fine again.

Re/ the NTP issue, this has been resolved after working with the host provider.
Re/ plugin install order, good to know.
Re/ your note on page builders and WooComm, figured you might say that. Was just wondering if others who have used these together might have some tips or feedback from their experience.

Thanks Phil
