本地很好，但是當我部署在 aws ec2 服務器上時，它卡在page.goto中，并出現 **errorERR_CONNECTION_REFUSED**
所以我嘗試為 GUI 安裝 TightVNC，與卡在 page.goto 中的情況相同
作業系統：aws ec2 ubuntu18.04 (30Gib)
aws 安全組入站：5000 TCP 0.0.0.0/0
5901 TCP 0.0.0.0/0
80 TCP 0.0.0.0/0
3000 TCP 0.0.0.0/0
22 TCP 0.0.0.0/0
443 TCP 0.0.0.0/0
5901 TCP ::/0

哪個 google-chrome: /usr/bin/google-chrome 我試過了 'executablePath: "/usr/bin/google-chrome"' 但與錯誤相同
在~/file_name/node_modules/puppeteer/.local-chromium/linux-991974/chrome-linux
我輸入“ldd chrome | grep not”時沒有顯示，我安裝了所有東西
我認為與 puppeteer 和 aws ec2 最相關，我搜索并嘗試過
關我什么事？請告訴我

ERR_CONNECTION_REFUSED表示目標站點正在主動拒絕來自您的服務器的連接。
AWS 和其他大型托管服務提供商的 IP 地址經常被商業網站禁止，以避免抓取和爬蟲，因為，讓我們面對現實吧，大多數時候 id 有人從 AWS 訪問它可能是一個機器人。
嘗試使用更不知名的提供商和/或購買一些代理。
