Error in service traefik

Hi, I am trying to install using single bench setup method (https://github.com/frappe/frappe_docker/blob/develop/docs/single-bench.md). But getting error when I run docker-compose up. Below is the error getting:
ERROR: for traefik Cannot start service traefik: driver failed programming external connectivity on endpoint frappe_docker_traefik_1 (4874b5ba649ee510ee8b49419951f06e5ea47aa8b6d411a930d89221fa4edbfa): Bind for 0.0.0.0:443 failed: port is already allocated ERROR: Encountered errors while bringing up the project.

I found the solution. I restored docker to factory defaults and ran docker-compose up. Issue is fixed
