lightsail instance, wordpress connect error

Hello After creating the instance(solly-2), I installed WordPress. https://lightsail.aws.amazon.com/ls/webapp/us-east-1/instances/solly-2/connect I installed it several times and saw the message that it installed successfully. I also set up DNS before installing and I have a domain address.

When I try to connect to the domain address to set up WordPress, I get an error. I tried 5 times and I see the same error message (ERR_CONNECTION_TIMED_OUT). Why is this happening? Please advise a solution
