long route recovery on sleep device

[iwanbk]

I tested the flutter mycelium macos app and i found that it got issue when the laptop put to sleep (in my case: >2 minutes of inactivity).

my test setup:

• macos mycelium app on macbook pro
• mycelium on Linux, on which i did ping

I expect that the ping will be recovered soon after the macbook woke up.
But many times, it still not recovered even after 10 minutes.

I thought that the problem is on the flutter side, so i implement restart mycelium on wake up event.

Then i also tested it using my own public node, and the recovery times are significantly faster, many times only around 5 seconds.
(after few tests, the recovery time getting longer. Restart mycelium on my public node solve the issue).

i copied the logs from threefoldtech/myceliumflut#69 (comment) here:
