Hi,
Have nginx running with SSL and is fine with the local IP of the server but will only resolve its hostname for a limited period. If I reboot it connects again.
Also, the default page for server is showing an Apache2 page although Apache is not running.There was a previous install of Apache however.
Help appreciated.

sites-available block is: (I put hostname in inverted commas as I believe server is a reserved name)
#
# Note: This file must be loaded before other virtual host config files,
#
# HTTPS
server {
listen 443 ssl http2;
listen [::]:443 ssl http2;
server_name _ "server.thekingsley.co.uk";

root /var/www/html;
index index.php index.html;


Help appreciated.

Further to this-
The hostname is resolved from the outside, but not locally.
