您好，请问之前可以直接打开的情况是相同的配置文件没有任何改动吗？

在您的描述中，当前[连接]按钮不可点击的原因应该是无法判断应用服务所在端口是否开放请您点击[进入目录]确认是否正常生成了server_session_info.json 并写入了正确的HOST PORT等信息

没改过配置文件，server_session_info.json 文件也有信息

{"HOST":"slurm_compute01","PORT":36857,"PASSWORD":"*******"}

从登录节点测试到计算节点的对应端口也是通的

您好，感谢反馈这个No web browser found不影响jupyterlab的启动下面是一个正常启动的jupyterlab。能请您继续等待交互式应用让系统多执行几次检查连接看看是否可以连接上吗？Jupyterlab有很多自己的重定向规则，可能连接会比较慢，如果还连不上您可以继续关注之后还没有没更详细的log输出
