Network issues after a while on some clients

Issues

I’m having a strange issue with the network connection on my two wled controllers.

Here is some information about my setup:

  • Both wled controllers are connected via my Ubiquiti Wifi.
  • I have both wled controllers setup in my OpenHab instance. OpenHab constantly updates the values via the wled api.
  • My network has a 255.255.0.0 subnet. The wled controllers are in a different subnet as dhcp clients and servers (like my OpenHab intance) are also in a different subnet.
  • One wled instance is running on an ESP8266 and one on an ESP32 and both have the issue from time to time.

The issue I’m having is that some clients have access the web interface, api and can also ping the wled controllers. (Like my openhab server) But some clients from a different subnet somtimes have no access at all. (Not even the ping is working)
After I’ve restarted the wled controllers I can access the controllers from all clients again for some time.

Is there some kind of limit how much IP’s can access the wled controllers or is this maybe a routing problem because of my subnet configuration?
