You can try the other DNS servers. The three are:
45.55.142.122
45.55.112.11
46.101.65.164
Also, check to make sure that LaneChange (the actual redirect handler) isn't disabled for your IP at: http://lanechange-controller.fortheusers.org/manage/
It should say:
No overrides for your IP currently exist.
DNS redirection will work normally.
If that still doesn't work, there are some more detailed troubleshooting steps you can do with a PC here: https://faq.fortheusers.org/#not-working
But it is possible that on some router/ISP configurations, DNS will not be able to be overridden, and the redirect won't work.
Even in those scenarios, CaptiveDNS should work, but that needs another device on the same network: https://github.com/browseDNS/CaptiveDNS
