you cannot increase your ram cpu online
you need additional hardware for it
anyway give it some time and it should confirm on its own
if not
use a third party wallet application
import your eos wallet and then try to make another transaction if it fails
I've tried to fix my EOS wallet issue which is identical to the problems that OP is facing, are you saying the CPU can increase if it's on hardware like PC or Laptop? Can you please drop me a process or tutor?
