ok append this to end of the default file:
server {
if ($host = purplenode.lv) {
return 301 https://$host$request_uri;
} # managed by Certbot
listen 80;
server_name purplenode.lv;
return 404; # managed by Certbot
}
that should fix the redirection from http to https
try this for the login problem:
change (the order):
index index.html index.htm index.php;
index index.php index.html index.htm;
