IP ISSUE: This is the most reported problem by users that they have executed wrong IP addresses and therefore the Client of Minecraft is unable to connect with a server. Minecraft is connected to the server using IP address and if the server recognizes the IP address then only it will allow the Client to establish a secure connection. The IP Adress you are using may also be allocated to several other users. So it is important to manually change the IP address from time to time.

Firewall: Firewall is a security wall of a system that monitors the connection of your PC and Internet, It may also be possible that firewall has blocked your connection to the server because of “False” Suspicious activity. To solve this issue you have to add games files to the firewall exclusion list and then only you will be able to solve this issue.

Outdated JAVA Version: Minecraft is a Java-based Progame (game), Therefore it needs the latest updated version of java on your system to work properly. If You update the Minecraft Client ( game) and your java is not updated then the latest version of Game might show issues due to server conflicts.
