A brand new from scratch installation in Docker installs fine and comes up and registers. The mongo 4.0 deprecation error persists even on a BRAND NEW installation from scratch. The resulting installation works fine for the admin, but no new users can join. All emails entered are invalid and the register a new account button never lights up. This is not a bad thing if the admin is planned to be the only user. Everything works fine and the workspace is registered and I can install apps too. I guess a system with no users will have no complaints. ---

Hi! Can you please give us more information? Server/console ogs? Anything more, **anything** that you can think of that may help us figure out the issue better? Like the compose file for example, project current file list, contents (all excluding private information), etc ---

Thanks so much for getting back to me. So, I had a chance to do several “from scratch” installations. I ended up solving my problem after almost four days. Let me link you to an article that I wrote summarizing my findings. [RocketChat New Installation - ScottiByte's Discussion Forum](https://discussion.scottibyte.com/t/rocketchat-new-installation)
