Required: You need to enable admin access to follow these steps.

For smooth operation of your VPS or Dedicated Server, you need to unblock port 2224. If server events are "stuck" because port 2224 is blocked, unblock the port and try again after 15 minutes.

For Windows servers, unblock the port using Windows Defender Firewall. For Linux servers, follow the steps below to use firewallD to unblock ports on the server. If you're using a different firewall utility, you may need to change this sample code.

Connect to the server via SSH. For help, see . Run this command:

     sudo firewall-cmd --permanent --zone=public --add-port=2224/tcp

Run these commands:

      sudo firewall-cmd --reload
      sudo firewall-cmd --list-ports

The second of these two commands verifies that the port is unblocked.

About Nydus:

Nydus refers to a pair of agent applications (nydus-ex and nydus-ex-api) running on your server that communicate with the server dashboard, providing resource metrics and performing server operations you've requested. The agent listens on port 2224.

Because the server dashboard and upgrades rely on these applications, blocking port 2224 - or removing these applications from the server - stops these features from working.

Note: You don't have automatic backups and will need to rebuild the server, which means that all the information on the server will be erased.
