Homeassistant takes over my router

I’m using duckdns for my homeassitant so I can access it remotely.
So what I’ve done is that I have portforwarded 8123 in and out and 444 in and 8123 out like always. However I’ve noticed recently I can’t access my router website and have to factory reset it.
My Linksys velop router is on local IP and as soon as I portforward the 443-8123 port the router website gets replaced by homeassistant. So when I try to browse I get to homeassistant.

I have to factory reset the router… I haven’t had this issue before, it just started to happen. What can I do to solve this?
