This log from above came from execution of exe script. This is something what scp tool (running in background for VPN transfer test) produces as the output when host is unreachable.

It means that the client node was trying to connect to the host node (192.168.0.7) but failed. This is the effect of node beeing unable to connect but it is not indicating any specific bug by itself. Sometimes node may be disconnected due to network problems so we expect to observe such logs.

Likely in this particular situation disconnection is caused by timeouts or any other known issue adressed under tasks:

• Failed to find node on relay server ya-relay#197
• NET - packet timeouts #2148
