I've deployed via Digital Ocean. But when I tried to register an account, I'm stuck with "An unexpected error occurred. Please try again."

The runtime logs showing:
23/Aug/2024:19:56:49 +0000 "OPTIONS /index.php/auth/register" 204

I've tried to add on the environment variables:
VITE_FRONTEND_URL : ${APP_URL}
VITE_API_URL_CLIENT : ${APP_URL}/api
VITE_API_URL_SERVER : http://localhost:80/api
APP_CDN_URL : ${APP_URL}/storage
APP_FRONTEND_URL : ${APP_URL}

Please help.

Are there any other errors in the log? Did you follow these steps here? Including setting an APP_KEY?

Yes, I've set the APP_KEY and JWT_SECRET and checked the "Encrypt" checkbox as follows:

The error in my network tab is

Request URL: https://domain.tld/api/auth/register
Request Method: OPTIONS
Status Code: 204 No Content

This looks like a CORS issue. Try updating APP_FRONTEND_URL in DigitalOcean to match your domain name.
