I am running Webstudio in Codespace. But opening the project throws "This site can’t be reached" err

A community member was able to configure Webstudio in Codespace, but when they tried to open the project, they encountered a "This site can't be reached" error. Other community members reported the same issue. One community member mentioned that the issue did not occur when they used VSCode and Docker. However, another community member stated that Codespaces is not a supported method and has been removed from the documentation. There is no explicitly marked answer in the comments.
