I am trying to deploy an api that uses puppeteer to scrape data from a public website. I have defined an environment variable namely PORT and set it to 3000. I don’t have any issues running puppeteer itself just that after deployment I am still unable to get any open http ports on 0.0.0.0.
Before my free instance went into inactivity, I was able to deploy the same program and host it on the web without issues but after the inactivity I seem to not be able to pass through this time out issue. These are my most recent logs below:

How can I fix this issue. Any assistance is highly appreciated.
