Linux Laravel错误消息：连接超时[tcp://192.168.0.18:6379]雷迪斯

我的laravel上有一个错误日志，错误如下：

production.ERROR: ReportCode:b6d6409159f16d3d1c6ac8059ffcfa77   Message:Connection timed out [tcp://192.168.0.18:6379]  Trace:#0 /var/www/html/moladin-api/vendor/predis/predis/src/Connection/StreamConnection.php(128): Predis\Connection\AbstractConnection->onConnectionError('Connection time...', 110)
#1 /var/www/html/moladin-api/vendor/predis/predis/src/Connection/StreamConnection.php(178): Predis\Connection\StreamConnection->createStreamSocket(Object(Predis\Connection\Parameters), 'tcp://192.168.0....', 4)
#2 /var/www/html/moladin-api/vendor/predis/predis/src/Connection/StreamConnection.php(100): Predis\Connection\StreamConnection->tcpStreamInitializer(Object(Predis\Connection\Parameters))

尽管192.168.0.18服务器上的redis服务运行良好，没有发现任何错误
