The WebSocket is in an invalid state ('CloseReceived')

[janwiesemann]

I just wrote a small app which received live measurements and then pushes them into an influx database. Sadly, I've been experiencing some issues.

I'm running this in a Proxmox LXC-Container using netcoreapp3.1. This issues seams to occur, when the LXC is getting backed up.

The project and source is available at: https://github.com/janwiesemann/tibberToInfluxDB. Not all functions use Tibber.SDK.NET, since it started without this library.

You can find the log below.

@janwiesemann did you figure this one out?

[janwiesemann]

@toini not really, I haven't had the time to do so. I've worked around this issue by hard crashing my application and using a systemd service to automatically restart it a few minutes later.

@janwiesemann I have a vague memory i saw something similar before and incorrectly interpreted some of the log rows indicating failure while it had actually been intended behaviour. However im not sure if this is a similar case.

Would you have any instructions on how i could reproduce this myself? What lead this situation?
