TeamViewer on a router?

Question

Information Security

Hello!
I accidentally stumbled upon an address http://192.168.0.10on my local network (router, three computers, smartphones), where it says:

This site is running TeamViewer.
Free Port 80 for other applications in advanced settings.

Such a stub appears from all devices, team viewers are definitely not installed on any device. Remains a router or provider.
Yesterday I demolished the router settings, changed everything, the stub disappeared for a while, then reappeared. How to determine where to dig?
Router Trendnet tew 711br
Provider Dom.ru SPb

Tough but 100% functional.
No. Not on the TeamViewer router, but on the provider's network.
From the router it goes to the provider's internal network, and there another gateway passes to another subnet. And this host is already there (192.168.0.10).
It is better not to try addresses not from your network: they will regard it as a scan and you will be left without an Internet.
