プラグインをインストールしたらアプリが再構築できなくなった

Digitalocean 1-click Discourse install

I think DO one click is not a community-supported setup. I think you should reset your droplet instead and go ahead with this one.

DigitalOcean Port Closed after Installation

I am sorry, if you used the DigitalOcean 1-click app then you should go to DigitalOcean support if you have any issues. We can only support the official Docker installation here.

I have no idea tbh but these past posts have made me wary of it.
