The one-loop polarization operator of neutral gluons in the background constant Abelian isotopic, H 3, and hypercharge, H 8, chromomagnetic fields combined with A 0 electrostatic potential at high temperature is calculated. The case when A 0 = 0 is investigated separately. The proper time method is applied. It is found that neutral gluons do not acquire magnetic masses in the background fields, in contrast to the charged ones. The application of the results are discussed.
