Operating System

Linux

Version of PolyMC

PolyMC 5.1

Version of Qt

Qt 5.15.10

Description of bug

The launcher was supposed to launch the game and immediately go to the server, but instead just launches the game in the main menu.

Steps to reproduce

First method:

• Create new instance (for example: vanilla 1.20.1)
• Run polymc --launch 1.20.1 --server mc.hypixel.net in terminal.

Second method:

• Create new instance (for example: vanilla 1.20.1)
• Open instance settings
• Open "Micellaneous" tab
• Toggle "Set a server to join on launch"
• Set "Server address:" to mc.hypixel.net

Suspected cause

For what reason does the launcher miss the argument.

Logs: Completely ignored arguments: [--server, mc.hypixel.net, --port, 25565]

Those arguments aren't supported by the game itself anymore, since the 1.20 snapshots

Thanks for the answer. Well, since this is not a launcher bug, then I close this issue.

It is a launcher bug, Minecraft replaced it with new --quickPlay arguments, so the launcher should use that when launching newer versions.
