Domain resolved to wrong ip address (no replies)

Hello Everyone,

I've enjoyed Wamp server for quite a long time and its been really nice!
Having a website hosted and using reverse proxy for programs like plex servers etc.
Although since 2 weeks I have discovered a problem with my server.

When I locally go to my domain it redirects to my router: 192.168.1.254
Also using any subdomain redirects to the router.
But from any external location it all works fine. The primary domain and subdomains.
Also no settings have been changed in my wamp server or my router.
It happened from one day to the other, anyone got a clue what it could be?

Thanks everyone!
