SC keeps logging me out

I have SC v9.3.006 fresh install on Ubuntu 18 LTS on AWS. I have configured server to not cache anything yet SC keeps logging me out. Sometimes it works for half an hour and sometimes it logs me out within a min or two. Where should I look for the logs to see what’s causing the auto log outs? Any help you can provide will be greatly appreciated.
