League of Legends players sometimes have trouble logging into their game clients. Several users have reported the “unable to connect to an authentication service” error and the “ League of Legends Failed to receive Platform SIPT” error. This usually occurs due to a defective internet connection, a disrupted firewall, or something else altogether. The “failed to receive platform SIPT” error can also pop up during the champion select phase or midway through a game.

According to a thread on Reddit, many players on the North American (NA) servers of League of Legends were facing client-related issues. One such error message that popped up was “Failed to receive Platform SIPT. Check the server status here.” North American players also complained about queues canceling by themselves, matches not getting accepted even after accepting them, and also loss prevention notices for games where there were no dodges.

One Reddit user pointed out that they had the same issue a couple of months ago and it lasted for two weeks. They added that they were unable to log in to the client or get into matches and that they were asked by Riot Games support to try a Virtual Private Network (VPN), following which the client worked. “After the next patch it fixed itself and I didn't need a VPN anymore.

This error usually arises when the internet service provider (ISP) limits downloads and users are unable to login and update the game, resulting in a "League of Legends failed to receive Platform SIPT” error message.
