VNC receives connection on wired but fails on WiFi

Hello guys.

I have an AP that provides WiFi to my home, it works as bridge and any device that connects to its WiFi receives IP from my router DHCP on the same subnet as my wired LAN. Its subnet is In the case of my laptop, I set static IP

I installed a VNC server on my laptop, but it never worked and I never bothered to take the time to try to diagnose it.

But now I’ve bought a USB-RJ45 adapter and connected my laptop bt wire… and I was able to connect to its VNC!

Now I’m troubled. VNC server is set as Allowed Application.

Is there anything I can try to find out what’s the issue?
