Re: Delete fortinet
Again, you haven't answered my questions or given enough details for anyone to offer you much support. If you aren't able or prepared to describe your configuration then it is very difficult for anyone to spend time helping you.
But, I would assume from your one line response you are connecting your personal phone (which you have full control of) to a WiFi network (a corporate or school network perhaps?) and seeing the Fortigate block pages when you try and access certain pages.
You cannot "delete" these- these messages are coming from a Fortigate within the network you are connecting too. It blocks access to these pages across the network depending on your profile and the security policies the network administrator has set. You see a replacement (or block) page when this happens.
So, as I said in my last response you need to speak to the network administrator of the network you are connecting too.
Hope that helps.
