Mobile logo not appearing when site is at an IP address

I am building a custom Discourse site and can’t figure out why, although I have set the correct image paths in “Settings”, the mobile logo does not appear in mobile views. It does appear correctly when scrolling down the topic page, and sits to the left of the topic title. Any advice? Or any advice on a workaround?

Support for stuff like that when using the raw ip address is flaky, try setting a proper hostname.
