Xwiki: Failed to extract Entity Resource Reference from URL [https://my.domain.com/bin/view/Main/]

when i deploy xwiki and visit the page i get the following stacktrace. i can't figure out whats wrong.

I am trying to connect to a MySQL Database (actually it's mariadb).

i should probably mention that my tomcat server is behind an nginx server which acts as a reverse proxy. this is also configured in the server.xml
