Modem appear offline in the app.

Hello, I changed the router a few months ago and noticed the app shows it as offline. I read in a post that it might take some time to appear in the app, so I waited. However, it’s been several months and it still appears offline—I can’t manage it or see connected devices. The internet is working fine; it’s just the app that isn’t.

I tried unplugging

I tried re installing the app
