I have an iPhone 7 running IOS 15.1 and am using 4g data to browse with, although on certain site pages and apps I am getting the error "Safari cannot open the page because it could not establish a secure connection to the server."
I have tried using a different browser and resetting my network settings but both have failed. On some sites, I am able to visit different pages but if I try to open a video/image/popup then I get the error message.
Any help would be appreciated.
