Unable to access traefik dashboard in local network but okay when outside of local network

Traefik Traefik v2
1

I have setup traefik dashboard on raspberry pi 4B using docker. My issue is that I cannot access the dashboard when I am connected to the same wifi network. I can access the dashboard using my mobile phone when I switch off wifi and use LTE network.

here is my docker-compose.yml file.
