Flutter Unable to connect to Chrome debug port

I get the following error when I run an empty flutter app for web.

Command run:

flutter run -d chrome

Error:

Unable to connect to Chrome debug port: 50848
 SocketException: Connection refused (OS Error: Connection refused, errno = 61), address = localhost, port = 50849

I tried from different flutter channels (stable, and main). Re-installed Chrome. Nothing works.

Excerpt of Flutter doctor.

    What worked for me was modifying /private/etc/hosts.

    Now it looks like:

    127.0.0.1   localhost
255.255.255.255 broadcasthost
::1             localhost

    You can try to specify the port like the following

    flutter run -d chrome --web-port 8080
//Or
flutter run -d web-server --web-port 8080
