Server Plugin: [ERR] BTC (Lightning): Error while contacting

As I debug https://github.com/btcpayserver/app/issues/209 I've noticed that one of the clients has troubles getting any payments. It seems connection to the hub gets closed.

```

Start by tracing BTCPayAppLightningClient.cs at lines 26, 83, and 125, then compare its listener flow with LightningListener.cs at lines 530 and 541. VSSController.cs line 99 and SubscriptionService also appear in the logs, but no reproduction or test is named. Done is not clearly defined beyond resolving the connection and payment-listening failures.
