7. Try a Different Server or Version

• The issue might be with the server itself (especially with cracked or modded servers).

• Try connecting to another known-good server.

• Test a different version using the Minecraft Launcher.

• Ensure all mods are compatible with your Minecraft version.

• Conflicting mods or outdated Forge can cause socket errors.

This error usually occurs when the client cannot establish a connection with the server within a specific timeframe.
