Connection issues from Windows, but works on Android phone on same WiFi

I often have conneciton issues on Windows via browser, volumio.local, and the IP won’t connect. IP cannot be pinged. Volumio is connected to WiFi, I can see from the router management page. I can connect from my Android phone, which is also connected to WiFi. After a while “it just works from Windows” I can’t say what I did to make it work. The next day, it works perfectly, but the day after it doesn’t work.

I have a Asus RT-AX92U router.

If you have sometimes a bad connection and you can hook it up by wire
I would advice to hook it up by wire it’s always there and stable.

Sometimes I can connect right away from startup of Windows, sometimes not, but then after Windows have been running, it can connect. Very strange. Windows or WiFi-router problem?
Android app connects always. I try to restart Volumio from the app, but Windows still won’t connect to volumio.local or IP address.
