The primary recently underwent its second observed major dimming event ($\\Delta V\\,\\sim2\\,$mag). We present new, resolved Chandra X-ray and UKIRT near-IR (NIR) data as well as unresolved optical photometry obtained in the dim state to study the gas and dust content of the absorber causing the dimming. The X-ray data show that the absorbing column density increased from $N_H<0.1\\times10^{22}\\,$cm$^{-2}$ during the bright state to $\\approx2\\times10^{22}\\,$cm$^{-2}$ in the dim state.
