And it says: As of Unreal Engine 4.24, support for the HTML5 platform has been migrated out of the engine to a public Platform Extension that can be maintained and improved by community members. Documentation for the HTML5 Platform Extension is hosted alongside the GitHub repository.
That is, Eipc Games does not officially support the Web platform?
Hey there @Staxcel! Welcome to the community! You are correct, HTML5 support became deprecated in 4.23 and the community support for it ended at 4.24.3 over on the Github repo. Supporting web builds was becoming increasingly worse in a myriad of ways and generally few users of the engine at the time still used it as a build target.
If you do require web builds and have the talent, you may be able to port the old source but the engine has changed decently since then so it would definitely be an undertaking.
