[Bug]: Login redirects back to login page and white screen after admin login (Docker Swarm + Traefik setup)

[PhyBruno]

What happened?

Hello!

After a long time adjusting my stack to run Affine with Traefik, I finally managed to start my stack successfully — there are no errors in the logs. However, I believe there is still a routing issue somewhere in my setup.

Even though I can access the URL and log in with my already created account (I successfully went through the setup process and created an account), when I try to access https://affine.mydomain.com.br (fictional domain), I get redirected back to the login page right after logging in.

Additionally, if I log out and log back in as admin, the login works, but the page remains completely blank — which makes me suspect that I’m being logged out immediately after login.

I didn’t make any special configuration during the Affine setup, so I believe the problem lies in my stack configuration.

It’s worth mentioning that I’m using Docker Compose with Traefik, and the stack is deployed via Docker Swarm + Portainer. I’m not sure if this could affect the behavior.

I’ve already tried setting the SERVER_URL to different values:

https://affine.mydomain.com.br

http://localhost

and also with ports 443, 80, and 3010 as well as setting the SERVER_PORT, but none of these made a difference.

Below I’m including my docker-compose.yml (with my real domain replaced by mydomain) and the .env file, both sanitized for security reasons.

Environment:

Docker Swarm + Portainer + Traefik

Affine (latest stable image)

Redis + Postgres services running as dependencies

Would appreciate any help or insight into what might be causing this redirect/blank screen issue. Thank you in advance!

Hi everyone! Could anyone help me with an issue I'm having with Affine?

I'd really like to use the tool, but I'm stuck on this.
