HA unable to connect to any entitys

Configuration
1

I can reach my WLEDs from my Pc, my Laptop, my Phone and so on. But whenever I try to add WLED to HA [IMG1]
The red Text says Connection Failed, i have WLED in German.
It takes a few seconds until the Error appears.
When i try to do it with http:// I get this:
[IMG2]
The “UNKNOWN ERROR OCCURED” happens instantly as soon as I press enter.

I have this Problem a bit longer now (2-4 Months, wasn’t really worried about it.)
I have Homeassistant installed via Truenas scale (Official catalogue). All my other Apps work fine, just HA can’t reach anything in my Secondary Network.

mDNS traffic does not cross from one IP subnet to another.

I am not an expert on networking but you could try assigning static IP addresses to your devices.

Thay have a static Ip-Adress (Server aswell as WLED). And HA was able to reach them before with no problem, then I made an Update for HA and after that it wasn’t working anymore.
