    <Logger name="com.alibaba.nacos.shaded.io.grpc" level="${nacosClientProperty:com.alibaba.nacos.config.log.level:-info}"
        additivity="false">
        <appender-ref ref="ASYNC-REMOTE"/>
    </Logger>

It should be modified to

    <Logger name="com.alibaba.nacos.shaded.io.grpc" level="${nacosClientProperty:com.alibaba.nacos.config.log.level:-info}"
        additivity="false">
        <appender-ref ref="ASYNC_REMOTE"/>
    </Logger>
