Riot Games' Repeated SSL Certificate Oversight Disrupts League of Legends Logins Globally

01/05/2026

At the start of a new year, a familiar issue resurfaced for Riot Games, leaving millions of League of Legends players globally unable to log into their accounts. The culprit: an expired SSL certificate, a technical oversight that remarkably mirrors a similar incident from ten years ago. This recurring administrative lapse turned what should have been a seamless transition into the new year into a frustrating experience for the gaming community.

On a recent Sunday, reports began flooding in across various platforms, indicating that players attempting to access League of Legends were stuck indefinitely at the game's initial loading screen. While Riot Games promptly acknowledged the problem and stated they were investigating, the community quickly pinpointed the core of the issue. After examining the client's error logs, players discovered that Windows systems were rejecting connection attempts due to an outdated SSL certificate. This revelation underscored a significant security protocol failure.

SSL (Secure Sockets Layer), or more accurately its successor TLS (Transport Layer Security), is a fundamental security mechanism designed to establish encrypted communication pathways between a server and a client. This process involves mutual verification of SSL certificates, which are digital credentials issued by trusted third-party authorities and require regular renewal. For instance, when you access a website, your browser and the server engage in an HTTPS handshake, validating each other’s certificates to ensure data integrity and prevent security threats like domain spoofing.

Interestingly, the League of Legends client operates as both a web browser and a web server, hosting internal web elements that it then requests for display. Players observed that the client attempts to establish secure HTTPS connections for this internal traffic, an unconventional design choice. This setup relied on a hard-coded SSL certificate within the application, which functioned correctly until its recent expiration. The oversight meant that, unlike automatically renewed external certificates, someone within Riot Games needed to manually ensure this specific certificate was updated.

While Riot Games has yet to officially confirm the expired certificate as the definitive cause, the evidence strongly suggests it. Players found a temporary workaround by manually setting their system clocks back to a date prior to the certificate's expiration, allowing them to bypass the login barrier. This clever solution by the community further corroborated the nature of the problem, highlighting the direct link between the certificate's validity and access to the game.

The historical context of this event adds an almost comedic element to the situation. A decade ago, on New Year's Day, League of Legends players encountered an identical problem: SSL certificate expiration pop-ups prevented game access. At that time, Riot Games confirmed the issue was due to a certificate that "should have auto-renewed" but didn't. It appears that any internal reminders or protocols established after the 2016 incident might have been overlooked or forgotten, possibly amidst significant client updates that occurred later that same year.

Following the recent disruption, Riot Games quickly rolled out a client update to rectify the login issues. This update reportedly involved extending the SSL certificate's expiration date to the year 2125, a seemingly extreme measure to prevent future recurrences for the next century. This proactive step aims to ensure that players will not face this specific problem again in the foreseeable future, marking a long-term solution to a twice-repeated error.

The recent service interruption for League of Legends players stemmed from an overlooked SSL certificate renewal, echoing a similar incident from ten years prior. This technical lapse, tied to the game's unique client architecture, left millions unable to play until Riot Games deployed a fix extending the certificate's validity by over a century, aiming to prevent such issues in the distant future.
