Firewall connection problem

[pornpoi]

I've found the problem when I deploy to the openshift (on premise) I got this error:

The process "PATH=$PATH:/usr/local/bin NODE_PATH=npm root -g node '/var/www/html/vendor/spatie/browsershot/src/../bin/browser.js' '{"url":"file:///tmp/52577805-0788178001630927001/index.html","action":"pdf","options":{"path":"/var/www/html/storage/pdf/20210906/bid_131.pdf","args":["--no-sandbox"],"viewport":{"width":800,"height":600},"displayHeaderFooter":false,"emulateMedia":"screen","format":"A4","margin":{"top":"10mm","right":"5mm","bottom":"5mm","left":"5mm"},"timeout":30000,"waitUntil":"networkidle0","printBackground":true}}'" exceeded the timeout of 30 seconds.

Then I try to allow all connection and It work then I think this problem from browsershot need to connection to 3rd party or some url for download some library

Could you help me which url that I have to allow to browershot
