local is fine but when i deployed on aws ec2 server it stuck in page.goto, and got a **error ERR_CONNECTION_REFUSED**

so i tried install TightVNC for GUI same as stuck in page.goto i checked google-chrome is installed, when i typing "google-chrome" on aws ec2 in tightVNC viewer, it can show chrome well

os: aws ec2 ubuntu18.04 (30Gib)

sudo node --version: v16.14.2

npm --version: 8.5.0

sudo npm --version: 8.5.0

google-chrome --version: Google Chrome 101.0.4951.64

which google-chrome: /usr/bin/google-chrome i tried that 'executablePath: "/usr/bin/google-chrome"' but same as error

in the ~/file_name/node_modules/puppeteer/.local-chromium/linux-991974/chrome-linux when i typing "ldd chrome | grep not" nothing show, i installed everything

i think most related with puppeteer and aws ec2 i searched and i tried

what's matter to me? please let me know

CodePudding user response：

ERR_CONNECTION_REFUSED means that the target site is actively denying connection from your server.

IP addresses of AWS and other large hosting providers are often banned by commercial sites to avoid scraping and botting because, let's face it, most of the times id someone visits from AWS it's probably a bot.

Try to use a more obscure provider and/or buy some proxies.
