For Greenlight regarding failure to withdraw funds:

I got this reply:

Hi Roland, thanks for reporting. We are currently dealing with a bunch of things that werent quite ready to handle the scale up last week. One of them was adding a load balancer, which has a shorter keepalive interval, and drops connections that were inactive for several seconds. We have a patch for the client library, but need to address a slow notification first which would otherwise worsen. So the command was delivered but the connection was dropped due to a slow response.

I guess we need to wait for them to apply the fix, and then update glalby to use the latest greenlight version.

LDK works well!

I wonder if we should just merge this PR and update glalby bindings once the greenlight issue is fixed.

[rolznz]

@rdmitr does that sound ok to you?

[rolznz]

@rdmitr we need to update the glalby bindings to support mac first though - could you update them here getAlby/glalby-go#5 and then consume the new commit hash?

[rdmitr]

@rolznz the bindings have been updated and merged 👍
