Hosting issue IP getting blocked
I'm having issues with a website that my father and I own. It appears that every IP address is getting blocked that a certain laptop touches. I've tried different IP addreses on different computers/phones and have been able to access the website. Once this specific laptop accesses the website nothing on any network will connect to it anymore. I've had my hosting service white list the ip's but I end up having to redo the white list after the specific laptop access the website.
Does anyone have any ideas what could be causing this on this laptop? Thank you for your suggestions.
