Sign-in Problems
The Microsoft window fails, says you do not own the game, or you keep getting signed out.
| What happens | What to do |
|---|---|
| It says you do not own Minecraft | Sign in with the Microsoft account that bought Java Edition. Bedrock, or a different Microsoft account, will not work. |
| Game Pass account fails | Open the official Minecraft Launcher once and launch Java Edition, so your Minecraft profile and username exist. Then try Sour Client again. |
| The window opens and closes, or never loads | Check your internet, then close the launcher fully (including from the system tray) and open it again. A VPN or strict firewall can block Microsoft's sign-in pages. |
| Signed out every time you open it | Sign out from the account menu, then sign in again. If it keeps happening, open a ticket. |
| Your session ran out | Microsoft tokens expire. Sign in again from the account menu; your settings are kept. |
Sour Client never sees your password: you sign in on Microsoft's own page and the launcher only receives the token Microsoft sends back.
