MMY app connection problems

When the MMY app spins on a loading screen or never sends the login code, the phone's connection settings are the first place to look. Three of them break the secure connection quietly.

A wrong clock

TLS checks the phone's clock against the certificate. A clock set by hand, or a clock left wrong after a battery pull, fails that check, and the app reports nothing useful: the screen spins, or the request simply never completes. Set the date and time to automatic. Settings, System, Date and time, or whatever the skin calls it, and turn on automatic date and time plus automatic time zone.

This is the check to do before any reinstall. A file problem fails at install with a parse error. A clock problem fails after install, on every secure request, and reinstalling changes nothing.

VPN and Private DNS

A VPN routes the app's traffic through another host, and a Private DNS provider answers the app's name lookups. Either one can block the host the app calls, and the symptom is identical to a dead server: endless loading, no code sent, assets that never finish. Turn the VPN off for the attempt. For Private DNS, set it back to Automatic under Settings, Network, Private DNS, and try again.

If the app works with both off and fails with them on, the block is in the VPN or the DNS provider, not in the app and not in the file. Leave them off while you use the app, or switch provider. Reinstalling will not route around a tunnel.

Metered connections

The first launch downloads game assets, and it will do that on mobile data if that is the active connection. On a metered plan that spends the allowance, and on a capped plan Android may pause large fetches it considers background. The practical fix is the one on the first launch page: do the first open on Wi-Fi.

Later opens reuse the stored assets, so the metered cost is a first-open cost, paid again only after an update or a data clear. If you cleared data to fix something else, expect the fetch to run once more and be on Wi-Fi for it.

Data saver, which some phones enable per app, can also hold the fetch back. If the first open stalls only when data saver is on, exempt MMY or switch to Wi-Fi. That exemption does not change permissions and does not affect the login.

Order to try

  1. Set date and time to automatic.
  2. Turn the VPN off and set Private DNS to automatic.
  3. Move to Wi-Fi and open the app again. Give it a minute.
  4. Still stuck: clear cache only, from Settings, Apps, MMY, Storage, then reopen on Wi-Fi.

Step four keeps the login. Skip straight to a reinstall only after these four, and read the uninstall page first if the phone carries two icons named MMY.
