Unable to connect to Home assistant with DuckDNS url on windows Laptop

HI Everyone,

I have a strange situationon my Windows machine. I currently use 2 clients to access the Home assistant hosted on Raspberry pi 4.

Starting some time ago, I see that i am able to access the Home assistant server using my IOS device (Connected to the same network as Home assistant & on 4g LTE network). Apparently the connection on windows machine does not work with the DuckDNS URL. On windows machine i am only able to access my home assistant server using the local IP

I also tried clearing my cache/ Cookies with a browser restart to check if the problem is gone. But ended up with no access to Home assistant

Assistance here would be appreciated
