Hi, I keep trying to run TS Search Dmol3 calculations and this error keeps appearing :

            Total Energy           Binding E                   Time   Iter

Ef       -13496.371472Ha       -22.2849651Ha                  78.4m     20

TS Search Status: Type, Search #, reaction coord, Energy

    LST      0      0.000000           -22.28496512

Unable to bracket maximum from both endpoints

Please check endpoints

Cumulative number of energy/gradient calls    :                 17

Message: Unable to bracket maximum from both endpoints

Message: Please check endpoints

Message: DMol3 job failed

Error: DMol3 exiting

I've changed smearing, RMS convergence, functionals, orbital cutoffs.... I don't know what to do anymore. Help please?
