Hi,
I have a Belkin ax3200 loaded with openwrt OpenWrt 22.03-SNAPSHOT r19575-506432a783. I have a simple setup where all my traffic is routed to a wireguard server. Recently (2nd time in 2 months). I kept getting connection errors to my wireguard server. Basically I get the following message in wireguard server.
[Sat Aug 27 03:40:31 2022] wireguard: wg0: Handshake for peer 3 (xxx:41586) did not complete after 5 seconds, retrying (try 10)
[Sat Aug 27 03:40:31 2022] wireguard: wg0: Sending handshake initiation to peer 3 (xxx:41586)
[Sat Aug 27 03:40:33 2022] wireguard: wg0: Handshake for peer 2 (xxx:50061) did not complete after 5 seconds, retrying (try 5)
[Sat Aug 27 03:40:33 2022] wireguard: wg0: Sending handshake initiation to peer 2 (xxx:50061)
[Sat Aug 27 03:40:34 2022] wireguard: wg0: Invalid handshake initiation from xxx:36159
[Sat Aug 27 03:40:36 2022] wireguard: wg0: Handshake for peer 3 (xxx:41586) did not complete after 5 seconds, retrying (try 11)
[Sat Aug 27 03:40:36 2022] wireguard: wg0: Sending handshake initiation to peer 3 (xxx:41586)
restarting/resetting openwrt does not fix the issue. Neither does changing the wireguard config to use a different key/setting.
The only workaround that I found was to upload my backed up settings to the server. (i sworn i didn't change anything since i backed it up).
