Hi,

every time I restart the server (2.4.7 from debian 10.4) i see weird floating 
requests, e.g.

May 22 19:27:52 qbs01 openvpn[16384]: Float requested for peer 1 to 1.2.3.4:5002

followed immediately by

May 22 19:27:52 server openvpn[16384]: TLS Error: local/remote TLS keys are out 
of sync: [AF_INET]5.6.7.8:9249 (via [AF_INET]192.168.2.3%vdsl) [6]

it is physically impossible that anything floats to the IP above as this is a 
fixed IP that never floats and always belongs to the client YYY

i thought nothing of it, as it everything would eventually resolve, until 
yesterday...

May 22 19:28:06 server openvpn[16384]: XXX/1.2.3.4:5002 TLS Auth Error: TLS 
object CN attempted to change from ‘XXX' to ‘YYY' -- tunnel disabled

remote client got 

May 22 19:28:07 YYY openvpn[492871]: AUTH: Received control message: AUTH_FAILED
May 22 19:28:08 YYY openvpn[492871]: SIGTERM[soft,exit-with-notification] 
received, process exiting

and that was it, game over, my VPN was down the whole night until someone woke 
me up az 5:30am Saturday morning and I restarted the client.

how is this possible? YYY always has the same IP and port 1.2.3.4:5002, the 
float requests to it are from random other clients, different every time.
