Website only works on mobile data

My website, crossfithollywood(dot)com, only works on mobile data or mobile hotspots. It does not work on wifi, I get an error “DNS_PROBE_FINISHED_NXDOMAIN” when I connect to wifi. how can I fix this?

It seems like a DNS cache issue. To fix this, try the following steps:

  1. Clear your device’s DNS cache.
  2. If you’re still experiencing the problem, try changing to a public resolver like Google’s or Cloudflare’s
