So recently I setup a webserver on windows 10 at my place (Frontend Angular 2). I setup all the necessary stuff like DNS, Hostfile, Firewall... Then I bought a domain and added my global ip to that domain. Everything worked fine until today, where my place had a power failure.
So I restarded the server and the router and noticed that I have a new global IP. So I changed the IP at the frontend and the backend and updated the IP at my domain name provider.
Now my problem is, that the domain isn't connecting to my webserver anymore - its timing out. But when I enter my global IP everything is working fine.
Any advices what I might have forgotten?
It turns out, that from the network where I'm accessing the domain it must have been some kind of domain caching. Because the domain is accessible for people that are not on the same network as I am. So it actually works, just not for me in my particular network.
