Playwright Error: net::ERR_CONNECTION_TIMED_OUT, Can't connect AWS

[yyanhan]

Dear developer:

I'm facing this error, that py playwright can't connect EC.compute.aws, do you have any experience with it?

playwright._impl._api_types.Error: net::ERR_CONNECTION_TIMED_OUT at http://ec2-3-131-244-37.us-east-2.compute.amazonaws.com:3000/
=========================== logs ===========================
navigating to "http://ec2-3-131-244-37.us-east-2.compute.amazonaws.com:3000/", waiting until "load"

Many thanks!
