Anybody else having problems with this?
As error code 59 is related to the login queue failing, simply restarting Valorant should do the trick to fix the problem. You can restart the game by clicking the ‘quit’ button on the error page, or press ALT+F4 to terminate the game entirely.
However, in some cases, a restart may not be enough. If you continue to encounter the error, we recommend rebooting your PC.
