We consider the family of singularity-free rotating black hole solutions in Einstein's conformal gravity found in Bambi C. et al., JCAP, 05 (2017) 003 and we constrain the value of the conformal parameter L from the analysis of a NuSTAR observation of the stellar-mass black hole in GS 1354–645 during its outburst in 2015. Our new constraint is much stronger than that found in previous work. Here we obtain (99% confidence level, statistical uncertainty only).
