How to resolve the issue of nacos unable to connect to the secondary nodes?

To solve the issue of nacos unable to connect to the secondary nodes, you can try the following methods:

1. Check the network connection of the slave node to ensure that it can access the master node properly.
2. Make sure the configuration file of the child node is correctly set up with the main node’s address and port.
3. Check the firewall settings between the master node and the slave node to ensure that communication between them is allowed.
4. Checking if the versions of the master node and the slave node are consistent is important, as having inconsistent versions may cause connection issues.
5. Try restarting the secondary node, as sometimes a reboot can resolve certain connection issues.
6. If the above methods are not effective, you can try reconfiguring the slave node or attempting to reconnect to the slave node using another method.
