Check Antivirus and Firewall Settings<\/h2>\n\n\n\n<p>Third-party antivirus or firewall software can occasionally flag or block Riot&#8217;s files mid-patch. You don&#8217;t need to disable your security software entirely \u2014 just make sure it&#8217;s not interfering.<\/p>\n\n\n\n<p>First, check your antivirus&#8217;s quarantine or protection history for a blocked Riot Client or League file, and restore\/allow it if found. Then add the <strong>Riot Client and League executables<\/strong> to your firewall&#8217;s allowed-app list; if your antivirus supports folder exclusions, add the Riot Games\/League installation folder too. Retry the patch afterward.<\/p>\n\n\n\n<p>Once Error Code 004 is fixed, you can get straight back to climbing. With our <a href=\"https:\/\/epiccarry.com\/lol\/boost\/wins\/\">LoL Wins Boost<\/a>, you can secure the ranked wins you need, break a losing streak, or push for the League Points required for your next division.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">6. Reset Winsock, TCP\/IP, and DNS<\/h2>\n\n\n\n<p>If a network-stack or DNS problem is interfering with the connection, reset Windows networking before a full Network Reset \u2014 it&#8217;s far less disruptive.<\/p>\n\n\n\n<p>If you&#8217;re using a VPN or proxy, disable it and retry first; Riot recommends connecting without one when troubleshooting. If your connection seems generally unstable, restart your modem\/router, pause large downloads, and try Ethernet instead of Wi-Fi.<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li>Search for <strong>Command Prompt<\/strong>, right-click, and <strong>Run as administrator<\/strong>.<\/li>\n\n\n\n<li>Run these one at a time:<\/li>\n<\/ol>\n\n\n\n<pre class=\"wp-block-code\"><code>netsh winsock reset\nnetsh int ip reset\nipconfig \/release\nipconfig \/renew\nipconfig \/flushdns\n<\/code><\/pre>\n\n\n\n<ol start=\"3\" class=\"wp-block-list\">\n<li>Restart your PC and retry.<\/li>\n<\/ol>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" width=\"1075\" height=\"600\" src=\"https:\/\/epiccarry.com\/blogs\/wp-content\/uploads\/2026\/08\/how-to-fix-league-of-legends-error-code-004-12.webp\" alt=\"How to Solve LoL Error Code 004: Admin Rights, Storage, DNS, and Client Fixes\" class=\"wp-image-40791\" title=\"Epiccarry\" srcset=\"https:\/\/epiccarry.com\/blogs\/wp-content\/uploads\/2026\/08\/how-to-fix-league-of-legends-error-code-004-12.webp 1075w, https:\/\/epiccarry.com\/blogs\/wp-content\/uploads\/2026\/08\/how-to-fix-league-of-legends-error-code-004-12-780x435.webp 780w, https:\/\/epiccarry.com\/blogs\/wp-content\/uploads\/2026\/08\/how-to-fix-league-of-legends-error-code-004-12-768x429.webp 768w\" sizes=\"(max-width: 1075px) 100vw, 1075px\" \/><figcaption><\/figcaption><\/figure>\n\n\n\n<div class=\"blog-info\">\n    <div class=\"blog-info-media\">\n        <img decoding=\"async\" width=\"130\" src=\"https:\/\/epiccarry.com\/wp-content\/uploads\/2026\/08\/lol-battle-pass-5.webp\" alt=\"LoL Battle Pass Boost\" title=\"Epiccarry\">\n    <\/div>\n    <div class=\"blog-info-text\">\n        <p class=\"main-text\" style=\"font-size:24px\"><strong>Buy LoL Battle Pass Boost<\/strong><\/p>\n        <p class=\"subtext\" style=\"font-size:18px\">Leave the grind to us!<\/p>\n        <a href=\"https:\/\/epiccarry.com\/lol\/boost\/battle-pass\/\" class=\"white-button\">Buy now!<\/a>\n    <\/div>\n<\/div>\n\n\n\n<h2 class=\"wp-block-heading\">7.
