Admin page not loading after customising UI

dilanwizzy

I decided to customise mailcow with a logo and a UI name change. After applying the changes, the webpage went down and after 2mins I was able to access it again. Only this time my admin page was inaccessible. Every time I access the admin page I get a “This site can’t be reached<MYDOMAIN> unexpectedly closed the connection.” on the browser I am using I have to wait 2min to be able to access the webpage again. Everything else works fine but I cannot access admin.

My mailcow instance is hosted behind a VPS. The connection is as follows.
Internet > VPS with wireguard port forwarding > Local network, Mailcow VM.

I have added the logs from when I clicked on "configuration
