I've been strugling with this problem for quite some time now, and i'm at my wit's end. I don't even have any idea what i could try to be looking for.
I have a raspi running with raspbian lite and lighttpd in my home LAN.
IP is obtained automatically and is currently at 192.168.1.3 I can connect to it per laptop (win10) and two desktop PCs (win7 & 10) with no problem at all.
The problem is, when i try to connect via my phone (Chrome on Samsung GS7E, Android 7.0, same result with "Samsung Internet"), i can not connect most of the time (though not always. there are days where i can connect without a problem...). The Browser says
This site can't be reached.
http://192.168.1.3/ is unreachable.
I have tried everything i can to find out why. restarted router/raspi numerous times, tried removing other devices from the network, different browsers on my phone. i tried remote debugging to see if there is any kind of information in the network tab, but i can't find ANYTHING and it makes absolutely no sense to me... Windows: works, Android: doesn't work.
I can also connect over PuTTy from windows.
JuiceSSH over Android:
no Route to Host
They are 100% on the same network, IP:port is 100% correct.
What are possible reasons for this behavior? how can it even exist in the first place? and how can i repair it? what are options/places i can check to see why this happens??
