Hi, Probably scf steps in phonon calculation is not converging, please check in between steps during phonon calculation or changing some parameter of phonon calculation this problem can be resolved like, alpha_mix(niter <https://www.quantum-espresso.org/Doc/INPUT_PH.html#idm36>), epsil <https://www.quantum-espresso.org/Doc/INPUT_PH.html#idm63>.
