Replit发布部署上线1小时后无法加载问题求助

我部署的Web应用在运行一段时间后会自动断开连接，找不到Replit部署出现该问题的原因。已完成官方故障排查流程，且确认以下配置无误：

• 启动命令为npm run start，端口配置为0.0.0.0，外部映射端口为80
• 已绑定并验证域名
• 账户已关联信用卡，排除欠费或超额问题

但部署仍会在上线一段时间后断开，唯一恢复方式是手动触发重新部署。

当前观测到的现象：

• 控制台及开发服务器无报错（开发环境运行正常）
• 访问时页面空白，显示ERR_NAME_NOT_RESOLVED，无法连接服务器
• 重新部署可成功构建，但运行时长不超过1小时（近48小时观测）

以下是我的.replit配置文件：

modules = ["nodejs-20", "web", "postgresql-16"]
run = "npm run dev"
hidden = [".config", ".git", "generated-icon.png", "node_modules", "dist"]

[nix]
channel = "stable-24_05"

[deployment]
deploymentTarget = "cloudrun"
build = ["npm", "run", "build"]
run = ["npm", "run", "start"]

[[ports]]
localPort = 5000
externalPort = 80

[workflows]
runButton = "Project"

[[workflows.workflow]]
name = "Project"
mode = "parallel"
author = "agent"

[[workflows.workflow.tasks]]
task = "workflow.run"
args = "Start application"

[[workflows.workflow]]
name = "Start application"
author = "agent"

[workflows.workflow.metadata]
agentRequireRestartOnSave = false

[[workflows.workflow.tasks]]
task = "packager.installForAll"

[[workflows.workflow.tasks]]
task = "shell.exec"
args = "npm run dev"
waitForPort = 5000

请问还需检查/更新哪些配置以确保生产部署持续运行？
