部署于某云的Linux服务器上,一直没出过问题,今日发现无法访问并抛出

经过测试redis服务没有问题,其他的linux服务器能够正常访问,且在开发环境中也能够正常访问
redis 配置如下:

spring.redis.database=0
spring.redis.host="host"
spring.redis.port=6379
spring.redis.password="password"
spring.redis.timeout=0
spring.redis.pool.max-active=-1
spring.redis.pool.max-wait=-1
spring.redis.pool.max-idle=8
spring.redis.pool.min-idle=0

补充: 从搭建了redis的服务器查看了一下redis (info命令)的运行状况为正常,且有另外3台服务器链接该redis且正常使用,而且这台服务器平时都正常运行,完全猜不到哪里会有问题,会不会问题在阿里云上?

再次补充
从无法链接的服务器 telnet Redis服务器显示被拒绝 而且我关闭了所有防火墙,且由其他服务器正常使用该Redis 这个问题实在让人费解啊 现在只能使用其他服务器代替该服务器了 很无语
