Common problemMinecraftJava Edition
Can't join a Minecraft server
Connection, firewall or router settings
When Java Edition can't reach a multiplayer server, the cause is usually on your side of the connection. Mojang lists unstable Wi-Fi, programs eating bandwidth, and a firewall, antivirus or VPN that blocks the game.
How to fix it
Close Minecraft and restart your device.
Sign out of your Microsoft account, close the game and sign in again.
Restart your router and close programs that use a lot of bandwidth.
Check that your firewall, antivirus or VPN is not blocking Minecraft.
Set your router to moderate or open NAT, or plug in an Ethernet cable.
