Problem with constant reconnection: "Camera errored: Camera closed connection. Attempting reconnection..."

[MindrustUK]

Just installed Hiksink (Standalone) and have it pointed at a Hikvision NVR. While it works, it keeps re-connecting as follows:

2022-06-15T11:01:59.543416Z  INFO hik_sink: HikSink MQTT bridge running

2022-06-15T11:02:50.806763Z  INFO Camera coms{camera=nvr id=nvr}: hik_sink::hikapi::camera: Camera connection established

Any ideas what could be causing this or if it's intended behavior? I would've thought connections should be persistent once established?

The NVR is probably returning responses HikSink can't interpret. Hikvision NVRs have been the worst offenders when it comes to non-conforming event streams, so I generally recommend pointing HikSink directly at the cameras. What is the model of the NVR? Can you enable DEBUG in the config and post the logs? Cheers.

Thanks for responding, the model of the NVR is: DS-7608NXI-I2

Log as attached: [nvr-debug.log](https://github.com/CornerBit/HikSink/files/8928574/nvr-debug.log

The NVR is closing the connection with HikSink. Can you take a look at the NVR side and see if there are any warnings in the logs?

As per attached screenshot, the notable event appears to be related to: "Remote: Alarm Disarming/ Remote: Alarm Arming", any thoughts?

[CornerBit]

That's a very strange message to show up! Accessing the event stream shouldn't perform any actions on the NVR. Can you check if your NVR is on the latest version?

I've just made sure to update to the latest firmware (V4.61.010 build 220606 ) still seeing the problem with the associated armed / disarmed messages. I'll see if I can turn up anything more with additional investigation...
