The plotted Corrected Flux vs. Time data (converted from NASA's K2 raw data by A. Vanderburg) were accessed by starting with his website https://www.cfa.harvard.edu/~avanderb/k2.html.  RED points are the major eclipses; YELLOW points are the minor eclipses.

24 MAJOR (i.e.: Total) Eclipses (E_12 missing due to a data gap):

                          Kepler K2-C1 EPIC-201382958: Eclipsing Binary

Discussion:
This K2-observed EB system is not listed in the SIMBAD online database.  It  is characterized by alternating total (flat-bottomed) and partial (V-shaped bottomed) eclipses (see especially the expanded Figures 2. and 3.) and is likely a semi-detached or contact type.
