Top three things to fix
Re-export the feed with a calendar that reaches further out, and set feed_info feed_end_date past your next service change.
Service data ended 1969 day(s) ago. When the calendar runs out, trip planners stop showing this agency even though the buses are still running. Riders are told the service does not exist.
Effort: Usually one export setting; export on a schedule so it never lapses again.
Add the required column named in the finding to the flagged file.
A file is missing a column that GTFS requires. Apps may reject the whole file, so riders could lose the affected routes or stops.
Effort: Often an export setting; ask your vendor if it recurs.
Add fare_attributes.txt (or Fares v2 files) with your fare structure. If your service is fare-free, ask to have it marked fare-free instead.
The feed contains no fare information. Riders see 'fare unknown' in trip planners and can't budget their trip; visitors are most affected.
Effort: A small file for most flat-fare systems.

Hi Flixbus team, Service data ended 1969 day(s) ago. When the calendar runs out, trip planners stop showing this agency even though the buses are still running. Riders are told the service does not exist. The fix is usually one export setting: Re-export the feed with a calendar that reaches further out, and set feed_info feed_end_date past your next service change. This came from your GTFS data quality scorecard, which checks the feed you publish and lists the fixes in plain language: https://gtfsscorecard.org/agency/flixbus/

The value does not need to equal the five-digit NTD ID; we do not have that ID on file, so the optional equality comparison is not checked yet.
