I have an issue where some network requests return
ERR_ADDRESS_UNREACHABLE and others resolve successfully.
Success and failure depends on the domain, for example requests to amazon.com resolve while github.com fails.
I can solve the issue until the next reboot by running
sudo dhcpcd wlp1s0, where wlp1s0 is my wifi network.
