I was making minor content changes to my Wordpress website (standard Ubuntu 18.04 droplet WordPress setup), and suddenly all my requests from my browser to are refused. Apparently, this only occurs to devices connected to my home router. I can access correctly with 4G on my phone, and my friends can access the website in their homes.
I suspected it might be a DNS cache problem. But I can SSH into the droplet using my domain, through my home router, without any problems. I also tested that the domain resolves to the correct droplet IP address on my desktop machine.
This is really annoying since I cannot access my site directly. Does anybody have any ideas what the problem might be?
