SYRIUS Atomic Swap Test Required Wallet Restart

@vilkris Please see issue I encountered below. Wanted to post here before creating an issue on Github.

Setup on TESTNET

Alice starts P2P with Bob. Alice locks 1000 tQSR.
Bob joins and locks 100 tZNN
Alice receives and swaps
Alice receives 100 tZNN.
Bob scans looking for secret.
After 3-4 minutes Bob did not find the secret. I had to restart SYRIUS to see the secret. The issues starts around minute 5 of the video.

Thanks for posting this. Has this only happened once? Were the two wallets using the same node?

It only happened once. I was using my node


I just realized that I was using a VPN and maybe that was causing the issue. Let me try without the VPN and see if that improves things.

Yep, I’m pretty sure the VPN was causing issues. Both VMs had VPN connections and both were showing strange behavior. I turned both off and issues have gone away.

Okay, I did some investigation and was able to reproduce the problem by intentionally cutting off the node connection while Syrius is scanning for the swap secret. The swap secret scanner does not gracefully handle that situation and terminates. This will have to be fixed.


Got it. Makes sense. My VPN seems to be unstable, and drops connections to my node constantly. Glad I was able to discover this.

The latest updates in the P2P swap branch should fix this issue. For some reason Github Actions isn’t working so Syrius will have to be built from source.

OK, I’ll try to test today.
