    Hi, I just see an error in Diagnostics.

    In the Connectivity > Connecting back to this site, there’s an error says:

    wp_remote_post() test back to this server failed! Response was: 403 Forbidden
    This additional info may help you diagnose the issue. The response headers we received were:

    Here is the screenshot.

    It seems related to Cloudflare but I don’t know how to fix this. I’ve searched the web but didn’t find the answer. I think there might be some settings that need to be modified?

    Thank you.

    Hi @barrelleaf, thank-you for your message and the detailed description of what you’re seeing.

    I have seen the wp_remote_post() issue come up recently where the Cloudflare firewall needed to have Wordfence IPs added to the whitelist, although sometimes this is also fixed by adding your own site’s IP to this list. Your site’s IP can be found at Wordfence > Tools > Diagnostics > Connectivity > IP(s) used by this server.

    For your information, our IPs can be found here: https://www.wordfence.com/help/advanced/#servers-and-ip-range

    • Login to Cloudflare
    • Go to “Firewall”
    • Click the “Firewall Rules” tab
    • Click “Create a Firewall rule”
    • Name the rule under “Rule Name”
    • Set the “Field” under “When incoming requests match…” to “IP Address”
    • Enter your site’s IP address under “Value”
    • At the bottom, under “Then…Choose an action” change “Block” to “Allow”
    • Click “Deploy”

    Return to your scan page and CANCEL the current scan and then start a NEW scan. Repeat the above process for our IP addresses if adding your own site’s doesn’t work.

    Let me know how you get on!

    Thanks,

    Peter.

    Hi @wfpeter, thank you for your response.

    I’ve seen 3 IP addresses in Diagnostics.
    It looks like this:

    172.104.79.XXX,172.67.176.XXX,127.0.0.1

    Should I add all of them in the Cloudflare using “And” or “Or”

    Hi @barrelleaf,

    Please use “or” in this context as only 1 IP will contact at any one time.

    Thanks,

    Peter.

    Hi @wfpeter,

    I’ve set it up. And since this seems related to the other thread, I will close this thread here.

    Thank you.
