The search for a consistent Gauge theory in Non-Commmutative (NC) is a longstanding problem with various solutions, non of them free from critisism. These theories break the Leibniz rule when using a non-constant NC parameter, Gribov copies appear induced by the non-commutativity of the space-time in the Landau Gauge and UV/IR mixing causes divergences on the NC Moyal plane. We propose three solutions for these problems. The first is to use the L infinity bootstrap to circumvent the failure of the Leibniz rule. The second proposal is to construct a Gribov region in NC Moyal space. The third proposal is to eliminate the UV/IR mixing divergence by renormalizing a Gauge theory on a NC torus. (AU)
