So this is very weird. Last night I went to turn off my light with my home automation app and I was disconnected from the WiFi.
When I went to fix it I realized that there is some problem preventing the phone from getting internet through the WiFi connection so, the phone was just ignoring WiFi. I can force it to connect without internet and I can reach local servers on my network.
It is like DNS is broken on the phone.
but check this out, it is not.
If I put the phone in airplane mode (to disconnect mobile data) and then force connect only WiFi, the internet does indeed work, even though it is reporting “No Internet“.
No other device on my network, WiFi or wired, has any problem.
Did you try workarounds such as resetting your network settings (circle arrow icon on top right in the wifi selection menu), or simply rebooting the phone?
That was probably it. Whatever that address is was not reachable for a few days for whatever reason. Could have been on my end but I don’t really want to dig through my router logs or do wire shark traces to find out.
