    Hi, my isp has enabled ipv6, thus meaning that everytime i login to whm, it logs me out saying ip address has changed.

    anyway to prevent this ?

    Thanks

    Hello,

    Could you review Effective Forum Threads and provide us with additional information about your system? Also, could you let us know the output from /usr/local/cpanel/logs/login_log and /usr/local/cpanel/logs/error_log when this happens?

    Thank you.

    Its your ISP be-bopping back & forth between ipv4 & ipv6 mine does it to
    only-way around it is to set Cookie IP validation to loose or disabled in tweak settings

    or just try logging in via the IPv4 address only

    My isp uses a range, i think a /64 range, therefore the ip changes within that range, as to why it keeps changing i have no idea. its something i need to speak to my isp about, as it should change unless the router reboots crashes, etc.

    I also have a similar issue with my mobile provider, which seems to change if you move closer to another tower.

    Your IP on these forums is a static IPv4 address. I wonder why your cPanel server is seeing your IPv6 address instead of that IPv4 address?

    Could you open a support ticket using the link in my signature so we can take a closer look? You can post the ticket number here so we can update this thread with the outcome.

    Thank you.
