Solution 1: Reset the IP address of the Internet

If you have not set the IP address to static, whenever the internet is reset, the IP address will be changed and IP address will no longer be matching. So, you have to restart the internet settings and clear the DNS cache. Here is how to do this!
First, reconnect the internet. Now connect to the server using the original IP address. Then check if the issue persists.

Solution 2: Updating the Firewall

Sometimes, it is the Windows Firewall that is causing trouble in connecting the game to the server. So, we have to make some exclusions to Windows Firewall to allow its proper connection to the server. Follow the following steps:
Click open the ‘Settings’ from the ‘Start’ menu. Now choose the ‘Updates and Security’ folder. Now open the ‘Windows Security’ and within it, choose the ‘Firewall and Network Protection’. Then click on the ‘Allow an App through Firewall’ option. Click open the ‘Change Settings’ and click ‘Yes’. Now choose the ‘Allow another app’ and then select the ‘Browse’.

Solution 3: Resetting the IP address

This is the easiest and the most successful solution so far! Because most of the people are not using the static IP address. It gets lost whenever you reset your internet. So, you have to check the IP address and update it in Minecraft launcher. Here is how to do this!
Open the Windows bar and type ‘Command Prompt’ in the search bar. Now, right-click to choose ‘Run as Administrator’. Now type the ‘IP config’ and then copy the ‘IPV4 address’ to remember it.

Now open the ‘Minecraft Servers folder’. Open the ‘Maxwell’, then open the ‘Minecraft Servers’ then ‘Server Properties’. Now keep in mind the ‘server port’ which is ‘25565’ in most cases. Now open the ‘Multiplayer’. Select the desired server and select the ‘Edit’ option.
Now enter the IPV4 address and the number we noted. For example, 192.xxx.x.xx:25565, where 25565 is the server port number. Now click the ‘Done’ and then ‘Refresh’. Your io.netty.channel.abstractchannel$annotatedconnectexception connection timed out error will be removed.

Solution 4: Turn off the Port Filtering

Many times you are not aware that your Port filtering is turned on and it is automatically filtering even the correct ports as well. It causes trouble in connecting to the gaming server due to continually changing Port Filtering.
You have to turn it off by changing the adapter connections of your local machine. Open the network configuration to fix it.
