Can’t connect to a website

[bobpet]

Trying to connect to arenapay.io I get a 502 bad gateway, but if I access via my cell phone with wifi off it works. Is there a setting incorrect?

Does this Orbi system have Armor or Parental Controls enabled?

What DNS servers are being used by the router?

[bobpet]

No on Parental and Armor controls

This error message implies that the Orbi router received invalid information when attempting to resolve the IP address:

https://developer.mozilla.org/en-US/docs/Web/HTTP/Status/502 

My first thought is to set the Orbi router to use different DNS servers.

A lot of people use:

CloudFlare   1.1.1.1 and 1.0.0.1

GoogleDNS    8.8.8.8 and 8.8.4.4

OpenDNS      208.67.222.222 and 208.67.220.220

This is set on the Orbi web interface, Internet menu, in the middle of the page.

p.s. Thanks to this post I now know that those URL's that end in unusual domains are actually Country designations.

*.io stands for Indian Ocean.

*.tv stands for Tuvalu.

(You might guess what I had naively thought they stood for.)
