WLed WebUi not reachable with smartphone

Issues
1

Hi,
one of my D1 Mini ESP32 is not reachable with my smartphone, not in the browser and not with the WLed App. If I check the notifications of the router it says that it has connected wiht IP xxx.xxx.xxx.123. But it is not shown in the WLAN Page of my router, but I can see the WebUI in the browser of my Laptop and I also can controll it with alexa. HyperHDR does also not see the device. What could this be?

And it is just one of my D1 Mini the other 5 are working correctly.

I would try rebooting that device and your router.

I allready did the reboot, but without any changes.

Some WiFi configurations may prevent clients connecting between each other. The so called “client isolation” or “guest mode”.
