Many Reddit users hit with "network security" block error on posts

Reddit users are experiencing a 'blocked by network security' error that prevents comments from loading on posts. The issue affects multiple browsers, including Chrome, Firefox, Brave, Edge, and Opera on both desktop and mobile. The error appears to be a server-side or front-end caching problem rather than an account restriction. The workaround involves refreshing the page, though it only lasts for one post before repeating itself. Reddit admin CorrectScale is investigating the issue.
