Hmm I have broken it.
I initially worked with just 192.168.1.100.. No /wordpress at the end.
I then changed the url to mywebsite/wordpress and the bellow option to just mywebsite (I have a domain name). It just redirects to my domains generic webhosting page.
I have it forwarding www quiries to my ip, and port forwarded to my pi.
When I put in my public ip I get to my website but content is missing and I can’t get to the admin panel.
