hvtymesync0:RTT on master and slave and clients openvpn down frequently

[fabiodanzetta]

Hello everybody,

we have two firewalls in HA and both are two Hyper-V VMs.
For about a month now our vpn connection established with openvpn client is constantly disconnected.
It can happen after 5 minutes, after 15 or after 2 etc.
Previously we had never had problems with disconnections and everything started for about a month.
In this period we have not changed any important configuration, indeed we have not touched anything fundamental for months.
I have enabled the deep log of the openvpn server and it would seem, from some online research, that it could be a problem related to an excessive network load and among the things they recommend is to switch from UDP to TCP.
But before changing the protocol in the openvpn server configuration I wanted to update the physical server to the latest patches and then also upgrade the firewalls but I also wanted to ask you something:
connecting to the console of the two nodes I noticed that both the slave and the master show the message you find attached.
Could it be related to the issue of openvpn disconnections?
And what does it mean?

Thank you all.
