Wordfence can't get the IP of clients... (10 posts)

    Got the following error.

    [Jul 20 15:10:35] Wordfence can't get the IP of clients and therefore can't operate. We received IP: 2600:3c00::f03c:91ff:fe73:b736. X-Forwarded-For was: REMOTE_ADDR was: 2600:3c00::f03c:91ff:fe73:b736

    I see this message over many days again and again.

    Could this be the cause of WF not functioning properly?
    How do I fix this?

    Wordfence doesn't support IPv6. Disable IPv6 for your website. This is usually done via your cPanel, or whatever your host provider uses for a control panel.

    Thanks sdayman! Much appreciated.

    For my education, how do you know the culprit is IPv6? Can you see this in the code I posted? I had seen another post about IPv6 but could not figure how you could see this from the error and ignored it.

    Could this cause other problems like WF not scanning daily?

    2600:3c00::f03c:91ff:fe73:b736 is an IPv6 address (longer format with more digits and hex)
    10.145.150.160 is an IPv4 address.

    Wordfence plain won't work with IPv6 enabled, hence the error message that "…can't operate"

    we say thank you, learned something.

    What do you mean with 'plain'? is there a 'non-plain' version?

    I meant plain as in "flat-out." Not as in "kind of" or "sometimes."

    I just talked to my internet provider and it is done automatically. The server responds with IPv4 or v6 as needed they claim.

    My host only offers IPv6 as an option, so I have it turned off.
    CloudFlare looks like it can feed your site IPv4 from IPv6 users.

    Thanks, I need to look in to this further.
