Connected but not receiving any data

Describe the bug
When I launch :MarkdownPreview, a new tab opens on http://localhost:8619/page/13, but I get Error Socket Not connected, followed by Error No Data Received followed by error connection reset/can't be reached. This only seems to happen on the new install I am on right now, on my other devices I didn't have this issue.

Desktop (please complete the following information):

• OS: Ubuntu 22.04, Brave Browser

No errors in neovim.

I've tried installing with yarn install (gives error, no such file or directory install), npm install(seems to build fine but connection error) or the build without yarn or npm(seems to build fine but connection error). Might this be an issue with wayland? That's the only big thing that seems to be different between my installs. Please let me know if there's anything other info I can add.
