Call to Wordfence API to resolve IPs failed

The error appears when the Wordfence plugin attempts to contact its cloud endpoint and the request does not succeed. DNS lookup failures, firewall blocks, or outdated plugin files prevent the API call from completing.

When the connection cannot be established, Wordfence logs the failure and aborts scans that rely on remote data.

Symptoms

[dashicons-warning]
Log entry shows error
Wordfence records “Call to Wordfence API to resolve IPs failed” with a cURL code.
[dashicons-admin-site]
Scans stop unexpectedly
Wordfence scans abort or display “Unable to connect to Wordfence servers”.
[dashicons-admin-tools]
Site Health warnings
Scheduled events related to Wordfence fail in the Site Health report.

Common Causes

DNS resolution failure
Server cannot resolve noc1.wordfence.com, resulting in cURL error 6.
Outbound firewall block
Port 443 outbound traffic to Wordfence IPs is denied by firewall or security group.
Cloudflare security rule
Cloudflare firewall or rate‑limit blocks requests to *.wordfence.com, returning 403.
Out‑of‑date plugin
Old Wordfence version uses deprecated endpoints or TLS settings.
