sentinel控制台没有显示客户端信息，app已经显示连接，但是没有具体埋点数据

控制台没有显示客户端信息，app已经显示连接，但是没有具体埋点数据； 控制台日志打印，被拒绝，报错如下：

2019-11-14 14:44:44 [pool-11-thread-1] ERROR c.a.c.s.d.metric.MetricFetcher - Failed to fetch metric from http://xxx.xxx.xx.xxx:8719/metric?startTime=1573713876000&endTime=1573713882000&refetch=false (ConnectionException: 拒绝连接) 2019-11-14 15:12:29 [http-nio-8080-exec-7] INFO o.a.coyote.http11.Http11Processor - Error parsing HTTP request header Note: further occurrences of HTTP header parsing errors will be logged at DEBUG level. java.lang.IllegalArgumentException: Invalid character found in method name.

加了tomcat 配置： maxHttpHeaderSize="8192"

还是报： ERROR c.a.c.s.d.metric.MetricFetcher - Failed to fetch metric from http://xxx.xxx.xx.xxx:8719/metric?startTime=1573724411000&endTime=1573724417000&refetch=false (ConnectionException: 拒绝连接)

telnet 端口 均可以，而且是内部局域网，没有其他限制，请各位大神帮帮忙。。。
