404 Error On Self-Hosted Install

Hello,

When I attempt a self-install, I get a 404 error when trying to login after setup. I am on Linux and use the docker-compose image, with the instructions found here: https://github.com/akaunting/docker. But a 404 error is all I see when attempting to visit the page after. Please advise on this. Thank you.

Update: now that I have accessed it over the reverse proxy URL, it sort of works? I see a page that's not a 404 now, but the installation prompt on the right to choose my language flashes on the screen for a split second and then disappears.

Update 3: (this is getting repetitive) now I have made it to the database screen (make sure there is no port attached to your reverse proxy url on the run.env file), but when I click next on the database page, nothing happens.
