In order for Minecraft to connect to its server, it must have the correct IP address tied to the correct port, and if you’re experiencing troubles with that, it won’t connect..

IP addresses change from time to time, but it’s not something we’re aware of until it has a negative impact on us, like these connectivity troubles.
