Swaps failed without sending a transfer proof
Hi there,
I've been running on mainnet and so far have had two swaps fail completely.
Here are the relevant logs (AFAICT) on both:
Swap dbf32b87-2a14-4848-a1a5-9bddd3e752da:

My ASB was up and reachable AFAICT throughout both swaps, though I saw similar lines to the below for each swap:
WARN Failed to get status of script: Failed to subscribe to header notifications: Made one or multiple attempts, all errored:
- CloseNotify alert received
txid=redacted
Let me know if there is any other data I can gather or provide around this.
Version: running the x86_64 artifact from https://github.com/comit-network/xmr-btc-swap/actions/runs/1141616002 to test the fix in https://github.com/comit-network/xmr-btc-swap/pull/649.

Important note I just realized -- both only refunded (or were seen by the ASB as refunded) after restarting the ASB client.
Unsure what to do about this, we may want to configure the electron client to do more retries in case the connection gets closed.
We added more retried to the electrum client in 0.8.2. Has the issue been resolved after upgrading. Would like to close this issue if so.

I unfortunately cannot test ATM, but retries should correct the issue as it was always resolved after an ASB restart (forcing a reconnection attempt to Electrum).
