I cant join me and my friends minecraft realm

When i was trying to join my friends Minecraft realm this morning and i afked over night the night before. I got on my pc and it said that my game crashed. i join the realm again and then i got the error code io.netty.channel.abstractchannel$annotatedConnectException: Connection timed out: No further information: I restarted my internet and did tons of troubleshooting. I called up my friend and told him to close and then open the realm. He got the same error when closing. I dont know what caused this but people said on this site that this was fixed but its not. Also the realm has 7 days left so that could also be the problem
