Help! Cannot log into HA remotely anymore (using DuckDNS)

Hello all, I am running HA using DuckDNS and everything was fine for about a month or two. Now I cannot log into my HA on my laptop.

I can access HA on my phone and my iPad. I can also access HA on my iPad using the Chrome browser. I cannot access HA on my one laptop on Chrome, IE or Edge.

I havent changed any network settings and have been accessing it with no issues for months and now all of a sudden it doesnt work. Any suggestions would be appreciated.

Any help would be appreciated!

I can connect using another PC or iPad but I just cant do it from my laptop.
