Quick Summary
Error code LC-208 in Minecraft typically indicates an issue connecting to Minecraft's authentication servers, often during the login process. This means your launcher is unable to verify your account credentials or server connection.
Common Causes
- Server-Side Issues: Minecraft authentication servers might be experiencing outages or undergoing maintenance. This prevents the launcher from verifying your account details. High traffic can also temporarily cause server instability.
- Internet Connection Problems: An unstable or interrupted internet connection can prevent the launcher from connecting to the authentication servers. This includes issues with your router, modem, or internet service provider (ISP).
- Firewall or Antivirus Interference: Your firewall or antivirus software might be blocking the Minecraft launcher from accessing the internet or specific Minecraft servers. These programs can sometimes mistakenly identify the launcher as a potential threat.
- Corrupted Launcher Files: Damaged or corrupted files within the Minecraft launcher can prevent it from functioning correctly. This can happen during updates or due to system errors.
- Outdated Launcher Version: An outdated Minecraft launcher version may not be compatible with the latest authentication protocols. Using an old version can sometimes cause this error.
Step-by-Step Fixes
Method 1: Check Minecraft Server Status
Step 1: Visit the official Minecraft status website (help.minecraft.net) or use a third-party service that tracks server uptime.
Step 2: If the servers are experiencing issues, wait for them to be resolved before attempting to log in again.
Method 2: Restart Your Internet Connection
Step 1: Power cycle your modem and router by unplugging them from the power outlet.
Step 2: Wait for about 30 seconds, then plug the modem back in. Wait for it to fully initialize.
Step 3: Plug the router back in and wait for it to fully initialize.
Step 4: Try launching Minecraft again.
Method 3: Check Firewall and Antivirus Settings
Step 1: Check your firewall settings to ensure that the Minecraft launcher (MinecraftLauncher.exe) and Java (if applicable) are allowed to access the internet.
Step 2: Temporarily disable your antivirus software and try launching Minecraft again. If it works, add the Minecraft launcher folder to your antivirus exceptions list.
Method 4: Reinstall the Minecraft Launcher
Step 1: Uninstall the Minecraft launcher from your computer.
Step 2: Download the latest version of the launcher from the official Minecraft website (minecraft.net).
Step 3: Install the launcher and try logging in again.
Method 5: Clear Minecraft Launcher Data
Step 1: Close the Minecraft launcher completely.
Step 2: Press the Windows key + R to open the Run dialog box.
Step 3: Type %appdata%\.minecraft and press Enter.
Step 4: Delete the 'launcher_profiles.json' file (this will reset your launcher profiles). You can also delete the entire '.minecraft' folder to perform a clean reset but this will remove your worlds and resource packs.
Step 5: Restart the Minecraft launcher and log in again.
