Having Issues Syncing My MFL League?

Here are the most common reasons MFL (MyFantasyLeague) leagues run into sync issues, and how to fix them.

Make sure you are using the right credentials

MFL leagues sync using your MFL username and password — not your Dynasty Nerds login. Double-check that you are entering your MFL credentials when connecting.

Check the league year

MFL requires a specific season year to sync. Make sure the correct year is selected when connecting your league.

Newly created leagues

If your league was just created on MFL, it may take up to 24 hours before it is detectable. Give it some time and try again.

Slow or stuck syncs

MFL's API can be slow during peak times (start of season, draft periods). If the sync appears stuck, wait a few minutes and try again.

Rosters look wrong after sync

If your league syncs but roster data looks off, MFL may not have processed a recent transaction yet. Try making a minor change on MFL to trigger a refresh, then re-sync in the app.

Lineup Optimizer note

MFL leagues are not supported by the Lineup Optimizer. Only Sleeper and ESPN leagues work with that feature.

Still stuck? Contact support with your MFL username and league name and we will take a look.
