World of Slime Steam Discussions — "it doesn't work" (Login Failed) ↗

The game stops on the landing screen with a "Login Failed" message, sometimes right after getting past an earlier starting-screen freeze.

Also appears as: world of slime login failed, world of slime login error, error al loguear world of slime, world of slime cant log in, world of slime server maintenance login

Multiple players in a single Steam Discussions thread for the World of Slime PC demo independently hit the same "Login Failed" dialog within hours of each other ("me too," reported twice by separate players), and one of them tied it directly to a server-side cause: "i cant get into the game... says server maintenance." A related thread that same week saw a player asking (in Spanish) whether login was even possible from South America after repeated failures, and a separate report of persistent connection failures was confirmed by another player as coinciding with an active "30 minutes maintenance" window. No official TEAM42 post has named "Login Failed" specifically, but the pattern across independent reports points at the server side rather than your own install.

What to try

  1. 01

    Check the Steam news hub and X for an active maintenance window

    Check the Steam news hub for World of Slime (app 4671450) and the @worldofslime_en account on X for an active maintenance window before troubleshooting locally — one player's connection failure was confirmed by another as coinciding with a maintenance period.

    Wait 15-30 minutes and retry if nothing official is posted

    If nothing official is posted, wait 15–30 minutes and retry. Reported maintenance windows during the demo have run in that range per Steam Discussions.

    No confirmed fix beyond waiting; report it if it persists

    No confirmed fix yet beyond waiting out maintenance. If it persists well past a posted window, report it in the World of Slime Steam Discussions with your region and the time it happened, so it can be matched against server-side problems. This page will be updated if TEAM42 posts a fix.
