  Besides the neutrino source detected by IceCube, NGC 1068, the association of
the IceCube-170922A neutrino with the blazar in a flaring state among several
wavelengths (from radio up to high-energy (HE) gamma-rays), the site and
mechanisms of production of HE neutrino remains in discussion. Extragalactic
sources such as Quasars, Blazars, Radio galaxies, and Gamma-ray bursts have
been proposed as progenitors of HE neutrinos. In this work, we study the
Blazars reported by Fermi-LAT in the 4LAC catalog, which are embedded inside
the 90\% error of the best-fit position from the neutrinos reported by IceCube.
We propose a one-zone lepto-hadronic scenario to describe the broadband
Spectral Energy Distribution and then estimate the number of neutrinos to
compare with those in the direction of each source. A brief discussion is
provided of the results.
