[Bug]: Admin "Already Created" When First Installed

[economist-ted]

Issue Description

When first pulling and deploying OpenSign, browser access goes straight to login and does not allow me to /addadmin at all. I haven't been able to get the other fix solutions to this issue to work, so I'm hoping it's because I'm using Ubuntu Server 26.04. I'd really like to use OpenSign over DocuSeal due to having more self-hosted features avaiable.

Expected Behavior

Upon first access in the browser, I'm expecting to be taken to a signup page to create credentials.

Current Behavior

Upon first browser access, I am taken straight to the login screen. When I attempt to add /addadmin, /signup, or /register, the screen says that an admin already exists. When I check MongoDB, there is a _User DB available, but it's empty. /app and /api/app extensions do not work either. I have attempted to change the ports, URLs, leave the URLs alone — nothing seems to work.

Steps to reproduce

1. SSH into home server
2. Install in dedicated ~/docker/opensign directory (editing the URL to the one you will be using)
3. Update URLs in .env.prod and docker-compose.yml to what you will be using via Cloudflare Tunnels/Zero Trust
4. Access in browser
5. Hit login screen instead of signup screen
