Why Does a Website Work on Desktop but Fail on a Mobile Network?

A mobile carrier or device may use different DNS, IPv6, proxy, or content filtering behavior than a home or office network. One network succeeding does not prove the domain resolves and serves correctly for all visitors.

What to check

Compare A and AAAA resolution, certificate and redirect behavior, proxy or CDN response, and network path across affected carriers. Record the exact error and test the hostname without relying on a previously cached browser session.

Recommended next step

Correct the authoritative record or edge configuration identified by evidence and test from more than one mobile network. Keep IPv4 and IPv6 behavior aligned if both are advertised.
