Stuck on login page

Dear Devs,
This time i tried to host the server in a Docker container.(Docker on Ugreen NAS if it matters, through the UI)
I cloned the repo, edited the .env file as in #20 suggested. (Switching localhost to the IP Address of the Server) Every container Works, I load the frontend Padge and tried to log in as default admin.
In the Inspector there was the following Error:

Firefox kann keine Verbindung zu dem Server unter ws://localhost:3030/socket.io/?EIO=4&transport=websocket aufbauen.

I tried the IP address of my NAS
Then the IPv4 Subnet and Gateway IPs replacing them with lockalhost
It did not work.

Here ist the protocoll from the docker:

Log_UG_docker.txt

and a diffrent protcoll from Docker:

export_log_20251126161828.txt

Should i Provide more information ?

Best Regards

I did mange to start the Server using SSH and docker compose.
How ever now the Frontend and backend is not working :(
