The Log has been filling up with the following messages every 15-30s:
wgRoad: L******9=: Handshake for peer did not complete after 5 seconds, retrying (try 2)
wgRoad: L******9=: Handshake for peer did not complete after 20 attempts, giving up

It seems to begin after the last upgrade to v7.14. Before that there was nothing in the Log until an actual attempt to connect happens. Is it bug or a feature? Shall I just switch the wireguard,info logging off?

Known issues, read the thread on 7.14 in announcements.

Great

Lesson learned --> smart adapters wait for 7.XX.1 or 7.XX.2, they never jump on 7.XX.0
