~30s delay after login before UI loads data

Hi,

I’m seeing a consistent delay of around 30 seconds right after logging in to the web UI.

After login:
The page loads
Then it takes ~30 seconds to populate devices, positions, etc.
After that, everything works normally
Realtime updates are fine
No performance issues during usage

The delay only happens immediately after login.

Environment:
Version: 6.12.1
Install: Docker + Swarm
Database: PostgreSQL + timescaledb
Devices: ~70
Server specs: vCPU: 8 | RAM: 32

Server doesn’t appear overloaded.
Feels like something related to the initial data query after authentication.

Any idea what could be causing this?

Thanks.

Check browser network console to see what takes so much time.

It seems like you have WebSocket connection problem.
