I got a problem about panel data,

I have micro panel data with 15.689 observation in 7 years. when i run hausman test, the results is to reject the null-hypothesis.
but, when i run Breusch-Pagan LM test, the results is also reject the null-hypothesis.

I am confused, what is the best model for my data? because i have one time-invariant variable so it's impossible to use FEM.
but i read from a book, if the true model is fixed effects, the random effects estimator is inconsistent.

Thanks before
