1. Firewall Permissions

a. If the Server isn’t Yours

If the server you are attempting to connect to is not your own, you must ensure Minecraft is permitted to connect by checking the firewall permissions on the server. You can get assistance with this from the server administrator.

The procedures for examining the firewall permissions on a Windows server are as follows:

• Launch the Advanced Security control panel for Windows Firewall.
• Simply select “Inbound Rules” in the left pane.
• Scroll down to the rule under “Minecraft (Java Edition)” in the right pane.
• To view this rule’s properties, double-click on it.

Ensure the All Remote and All local connections checkboxes are ticked in the Allowed Connections section.

b. If the Server is Yours

The following steps can be used to resolve the IO Netty Channel Abstract Channel Annotated Connect Exception error if the server is yours:

• Start the server again.
• Verify the server’s firewall settings.
• Verify that the most recent Minecraft version is installed on the server.
• Make support requests if you are using a third-party hosting company.

2. The Firewall is Blocking the Access

The Firewall on your machine may prevent Minecraft from connecting to the server, which may result in the IO Netty Channel Abstract Channel Annotated Connect Exception problem.

The following steps can be taken to resolve this issue:

• Restarting the router can occasionally resolve problems with network connectivity. Simply unplug your router’s power cord, wait a few minutes, and then plug it back in to accomplish this.
• Verify the app permissions for the Firewall. Your computer’s Firewall may be preventing Minecraft from connecting to the server. Open the Windows Firewall with the Advanced Security control panel to view the permissions granted to apps by the Firewall. “Inbound Rules” can be selected in the left pane. Scroll down to the “Minecraft (Java Edition)” rule in the right pane. To view this rule’s properties, double-click on it. Make sure that “All local connections” and “All remote connections” are chosen in the “Allowed Connections” section.
• Windows Defender Firewall should be disabled. Windows 10 has a built-in firewall called Windows Defender Firewall. It occasionally prevents Minecraft from contacting servers. Open the Windows Defender Firewall with the Advanced Security control panel to disable Windows Defender Firewall. “Outbound Rules” can be selected in the left pane. Scroll down to the “Minecraft (Java Edition)” rule in the right pane. To view this rule’s properties, double-click on it. Choose “Block the connection” under the “Action” heading.

3. Port Forward the Network

You can use port forwarding to connect to a server or service on your local network from the internet. It’s conceivable that your Firewall prevents Minecraft from connecting to the server if you receive the IO Netty Channel Abstract Channel Annotated Connect Exception issue. This issue can be resolved with port forwarding by enabling Minecraft to connect to the server through your Firewall.

You will need to know your computer’s IP address and the server’s port number you are attempting to connect to port forward. After that, you can direct traffic on that port to your computer using the router’s settings.

Here are some other port-forwarding pointers:

• Verify that you connect to the server using the correct IP address and port.
• If your IP address is dynamic, you might need to modify your port forwarding settings each time it changes.
• After port forwarding, if you are still having trouble connecting to the server, you might need to ask your ISP for assistance.
