Can't Join!

I keep trying to join everyday but this keeps popping up! It keeps saying "Can't connect to default or fallback server" And it says under it "io.netty.channel.AbtractChannel$AnnotatedConnectException" I use 1.14.4 with optifine! Please fix so I can play. My username is NuggetPlays! Minecraft_1.14.4_12_10_2019_3_37_39_PM
