Installing NC13 on centmin LEMP, secure check needed

MeiRos · March 14, 2018, 10:15am

I’ve been reading and testing a lot but still not sure if I made a secure installation or not.
Can someone who knows better take a look at my settings if they are ok?

Of course here’s not all config files…

My Nextcloud is working but the security… How could I know if there’s something badly open? Nextcloud’s test site didn’t find problems. Admin page is ok. SSL test gave A. Of course there’s always fine tuning but the question is: Is there something totally wrong?
