What is the problem here?
You did not provide all information on your configuration, this makes it very difficult.

I suggest you try "denyinterfaces eth0" as the last line in dhcpcd.conf after removing the static ip address from the DHCP range.

That is a definitive maybe as I have been able to get it to work using Stretch but I have not tried since then.

IIRC the only change needed was "usbhid.mousepoll=0" in cmdline.txt

Re: Fixing incorrect undervoltage warnings

The stock answer is use an official power supply to confirm that there isn't an issue with the power supply in use. If you still get the undervoltage, then you ask again. Yours appears to be the first reported case where a known good voltage is still firing the warning. I have observed a problem wi...

Re: Apache2 server times out on public IP address

I suggest that you look onto the router for the external IP and compare this with the IP given by whatsmyip, if these are not identical then the problem is with your ISP using CNAT. Apparently they are not identical for some reason. I am also using the noip2 client to keep my dns updated. Thank you...
