This neutrino belongs to Gold events, which more likely have an astrophysical origin. Among the two $\\gamma$-ray sources within the neutrino's positional uncertainty region, we find that one of them, the BL-Lac--type blazar PKS~2254+074, had a $\\gamma$-ray flare at the arrival time of the neutrino. The flare is determined to have lasted $\\sim$2.5 yr in a 180-day binned light curve, constructed from the data collected with the Large Area Telescope (LAT) onboard {\\it the Fermi Gamma-ray Space Telescope (Fermi)}.
