Connecting to Wordfence servers (https) with IPv6

    I have been exploring the option of running a server with only IPv6 connectivity, hosting WordPress and Wordfence, all behind Cloudflare for acceleration and IPv4-to-IPv6 connection proxying.

    Wordfence is showing the error: “Last rules update for the Wordfence Web Application Firewall was unsuccessful.” The issue seems to be that my IPv6-only server running Wordfence tries to connect to noc1.wordfence.com, which is IPv4-only, and my server cannot reach it.

    The diagnostics page in Wordfence Tools shows an error in “wp_remote_post() test to noc1.wordfence.com failed! Response was: cURL error 7: Failed to connect to noc1.wordfence.com port 443 after 2 ms: Couldn't connect to serve“. Connecting back to this site and connecting back to this site via IPv6 work since they go through Cloudflare.

    Would it be possible to provide IPv6 access for Wordfence rules updates?

    dig noc1.wordfence.com

    ; <<>> DiG 9.18.30-0ubuntu0.24.04.2-Ubuntu <<>> noc1.wordfence.com

    Hi @jruizjimenez, thanks for getting in touch about this.

    This is the first request we’ve had for public IPv6 addresses for noc1 and/or Wordfence Central, as I expect most WordPress users with IPv6 aren’t attempting to use an environment entirely without IPv4 at the current time.

    As we’re unable to follow-up on requests here on the forums, we eventually set topics such as this to “resolved” but it is still an open request in our internal issue tracker, so will document any alterations to the plugin or services in our changelog.

    Thanks,
    Peter.

    Thanks, @wfpeter . I’ve decided to add an IPv4 address as well. WordPress updates work perfectly on an IPv6-only host, but some plugins I need aren’t IPv6 ready. Email (SMTP) is also an issue since many servers aren’t prepared for IPv6.

    Thank-you @jruizjimenez for the clarification, we have noted your request and will be discussing it.
