      abstract     = {AT2021afpi was a 10 mag outburst seen by the MASTER-Tavrida
                      autodetection system in temporal coincidence with the
                      astrophysical neutrino candidate IC211125A. The object was
                      observed as an optical bright transient, initially
                      classified as a classical nova. Follow-up observations by
                      the VERITAS instrument at gamma-ray energies > 100 GeV on
                      the nova location resulted in no detection for an exposure
                      of 5.5 hours. Further spectroscopic reports reclassified
                      AT2021afpi as a dwarf nova of the type WZ Sge-Type, which
                      are not expected to be neutrino emitters. A possible blazar
                      detected by Fermi-LAT, 4FGL J0248.0+2232, which lies within
                      the $90\%$ localisation region of IC211125A, was observed in
                      a flaring radio state four days after the neutrino alert. A
                      further combined analysis with 1 hour of exposure time on
                      4FGL J0248.0+2232 at the position of AT2021afpi still
                      resulted in no detection.},
