Hello Ivan,

It is hard to say without looking into configurations of both of your HA
peers.

I guess the first question is whether the server that takes over the
traffic from the failed partner sends an OFFER (according to your logs)
and this OFFER doesn't go through the network, or the OFFER is not
generated by the server. Also, when you're expecting those offers do you
observe the server which should send this offer being in the
"partner-down" state (according to logs)?
