asyncio.exceptions.CancelledError when connection drops

[basslet]

I keep having this recurring log entry created by custom_components.remote_homeassistant

My main and remote unit are connected via Powerline, which is occasionally a bit unstable. Remote homeassistant seems to have an issue when connections drop.

Core 2025.1.1
Supervisor 2024.12.3
Operating System 14.1
Frontend 20250106.0
Latest remote home assistant and HACS

This error originated from a custom integration.
