First check who is seeing the error: only a bot or integration, all visitors behind a CDN or proxy, or regular visitors and WordPress administrators. That pattern points to different next steps—and a social preview failing on its own does not prove the whole site is down.
Start by identifying who is affected
Check the exact URL, the service reporting the error, and when it began. Then test the same page as a regular visitor and, if relevant, in WordPress administration. Use the pattern below to choose a branch:

| What fails | Likely layer to investigate | First action |
|---|---|---|
| Social previews, bots, monitoring, or integrations only | Hostinger server-level limits on automated traffic from certain network ranges | Check service status, retry later, and use exponential backoff where available |
| Visitors routed through more than one CDN or proxy | Proxy/CDN configuration that changes how requests reach the hosting server | Check the routing setup and keep one CDN or proxy active |
| Regular visitors or WordPress administration | Hosting resource limits or a WordPress plugin, script, theme, or custom rule | Check CPU and RAM usage, then test recent application or configuration changes |
HTTP 429 is a rate-limit response, not proof by itself that the server is overloaded or that WordPress is responsible.

If only automated services or link previews fail
Hostinger documents server-level limits for automated traffic from certain network ranges. Its examples include social previews on Facebook, Instagram, and WhatsApp; automation through Zapier, Make, and n8n; CRM/API synchronization involving HubSpot or Salesforce; and uptime monitoring. Hostinger says ordinary visitors can still access the site during this type of limit. The limit is described as applying across customers at the server level, rather than being tied to an individual plan or domain (Hostinger Help Center: server-level rate limits for automated traffic).
#1 Best Overall
- Check Hostinger’s status page for an infrastructure notice.
- Retry after a short interval instead of sending repeated requests immediately after each 429.
- If the integration supports retries, configure exponential backoff so the delay increases after successive failures.
Hostinger says high-activity periods of this kind typically resolve within a few hours; that is a general expectation, not a guaranteed recovery time for a particular site or integration. Changing hosting plans is not a targeted fix for this server-level limit.
If the domain uses Hostinger CDN and another proxy
Check whether Hostinger CDN and Cloudflare proxying are both active for the domain. Hostinger advises against routing a domain through both at once. A proxy in front of Hostinger CDN can make the hosting server see requests as coming from only a small number of proxy addresses. That can cause per-visitor limits on the hosting side to affect many visitors together.
Rank #2
- Review the domain’s CDN and proxy configuration and identify every active proxy layer.
- Remove the double-CDN arrangement and keep one CDN or proxy active.
- Use Hostinger’s CDN configuration guide for the relevant DNS and proxy setup.
If Hostinger CDN is active, inspect a failing request in your browser’s developer tools. Select the request returning 429, note its URL and time, and look for the x-hcdn-request-id response header. Hostinger says a 429 behind its CDN almost always comes from the hosting server or a plugin; the CDN itself returns 429 only as a last-resort protection at attack-level request volumes. The header and request details can help narrow down the failing path, but do not by themselves prove which component applied the limit (Hostinger CDN: 429 Too Many Requests errors).
If regular visitors or WordPress administration are affected
Check hosting resource usage
In hPanel, open Resources Usage and review CPU and RAM. If the site is reaching its plan limits, reduce resource use or consider whether the load is temporary or persistent. A temporary resource boost may help with a short-lived spike that reaches a plan limit; a persistent limit may warrant evaluating a hosting upgrade. Neither step is a general fix for every 429.
Test WordPress components and custom rules
A security plugin, another plugin or script, a theme, or an aggressive custom .htaccess rule may contribute to the response. Hostinger specifically suggests temporarily deactivating a security plugin, such as Wordfence, as a test. A plugin may deliberately return 429 when it detects repeated requests—for example, through login limiting, form-spam protection, or API rate limiting.
- Record recent changes and the current error pattern before changing anything.
- Temporarily deactivate a suspected plugin and retest the affected URL. If the cause is unclear, disable plugins in a controlled sequence so you can identify which change affects the result.
- If a plugin test does not explain the error and a theme change is plausible, try a default theme temporarily.
- Update WordPress core, themes, and plugins. Review custom
.htaccessrules for overly broad IP-range blocks. - Restore components after each test and record the result. Avoid leaving security protections disabled once the test is complete.
Hostinger’s broader troubleshooting guidance also lists high request volume, resource limits, attacks, and faulty plugins or themes as possible causes. Those are possibilities to investigate, not a diagnosis of any particular site (Hostinger: 429 Too Many Requests troubleshooting).
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.When the first check does not explain the error
Keep the scope narrow as you investigate: compare the exact failing URL and time across a regular browser visit, WordPress administration, and the affected integration. If only automated requests fail, follow the automated-traffic branch; if all traffic passes through multiple proxy layers, verify that configuration; if human visitors or administration are affected, use resource data and controlled WordPress tests. A 429 alone cannot distinguish these causes.
