尝试各种方法均无效。包括更新tomcat的war包、重启tomcat。
应用部署在三台机器上面，全部失去连接。
在nginx上面查看日志，产生了一堆错误日志。
其中包括了
2022/08/30 00:28:27 [error] 22365#0: *614206407 connect() failed (111: Connection refused) while connecting to upstream, client: 10.13.136.141, server: localhost, request: "POST /icore-pss-svr/service//com.h...nStdSicService/Getabc HTTP/1.1", upstream: "http://10.00.000.4:8002/ixxxStdSic", host: "10.00.00.10"

网上查询了下其他人的解决方法。最终服务器自己就好了。
