Hi, I have two devices running OPNsense 20.1.1-amd64, both configured almost identically.
One device is running without errors, on the other device I have the following effect:
If the device runs for a few minutes, I suddenly can't reach the web UI or LAN interface anymore.
Sometimes it helps to unplug the network cable and plug it in again. Sometimes I also have to restart all services via serial console.
What could be the reason for this?
How can I find out?
P.S. I have already restored the factory settings of the device and reconfigured it afterwards.
I just solved the problem myself: The IP address of the LAN interface already existed in the network and thus caused a conflict.
Thanks for reading the posting and no offense :-)
