We present an update of the survey of Active Galaxies with the High Altitude Water Cherenkov (HAWC) gamma-ray observatory.This work adds 567 days of HAWC data to the previously published survey, providing a refined analysis of an updated total exposure of 2090 days.The sample includes 138 nearby AGNs from the 3FHL catalog.We fit a modified power-law to their very high energy spectra, including the exponential attenuation caused by the Extragalactic Background Light.We found four sources with significant detections (above 5): the radio galaxy M87 and the BL Lac objects Mkn 421, Mkn 501 and 1ES 1215+303.We also report eight sources with a marginal detection (between 3 and 5) of which seven are classified as BL Lac objects and one as a radio galaxy.
