Your ROOT_URL in app.ini is https://git.cloudchain.link/ but you are visiting https://dash.bss.nz/open-source-mirrors/homepage/commits/commit/b73d36fbd4e495ea39985cf2e063ff4d0bf763e1/.devcontainer/Dockerfile
You should set ROOT_URL correctly, otherwise the web may not work correctly.
devcontainers can be used by IDEs like VSCode to build the whole development environment in a container.
This allows you to keep dependencies, build, and all development aspects separated from any development.
It also allows contributors to instantly have a working, standardized development environment.
It also allows cloud development tools like GitHub Codespaces be automatically setup with the desired environment.
