Thanks Agricola! You have been extremely helpful for a noob like me. Sorry to keep peppering you with questions but when it comes to replacing server_name nextcloud.*; with server_name yoursubdomain.*; my subdomain indeed is something like yoursubdomain.duckdns.org. This means that what I insert will look something like my_server_name yoursubdomain.duckdns.org.*; correct? My second question feels really dumb to ask but where can I look to find my server name?
Again, thank you for the remedial training. Also, as a preacher myself, I am grateful for your wife's jabs to keep you awake.
No, it would just be yoursubdomain.* (do not add duckdns.org the .* indicates anything after your subdomain is basically a wildcard)
