 Nacos 2.0.0 Compatibility Documentation

Solution: Open the port number for gRPC communication.

For example: the default port number of nacos is 8848, then you need to open 8848+1000=9848, 8848+1001=9849.

The port number used by nacos in my project is 5555, so I continue to open 6555,6556. Then no error will be reported.

connection succeeded:
