Login cookies rejected on .my.id domains, missing multi-part TLD supportRetry
When deploying OpenPanel on a .my.id domain (for example: abc.my.id) using Coolify, the login API succeeds and returns a success response, but the browser rejects the authentication cookie because the generated cookie domain is invalid.
As a result:
- Login request succeeds
- UI displays "Successfully signed in"
- Browser blocks the Set-Cookie header
- User session is not created
- User cannot proceed to the dashboard
