Cant view laravel sail project from localhost or localhost:80/Can not still view project even if port is changed from port:80 to another port in docker-compose.yml file

while following the documentation on how to build a new laravel sail project in docker, I run into an error at command [./vendor/bin/sail up] which shows something was running on port:80. I tried to stop the process running on port:80 but I could not so I changed the port number in the docker-compose.yml file to port:8080 and run the [./vendor/bin/sail up] command again an app was able to run in docker successful but the last output showed app was running on localhost:80 which was weird because I changed it. I tried accessing localhost:8080 but site could not be reached. I tried localhost/localhost:80 but it showed only a text [it works!] which is the apache2 localhost file. I tried docker-build and up, but still the same problem. I also tried docker-compose build --no-cache but still the same error. I also tried following laracast tutorial for sail laracast but still the same.

Any help would be much appreciated :).
