I made upgrade on our HA cluster.
Slave node upgraded OK based on mlos2-upgrade.log All services are ok, proxy servers internet pages BUT applience can not communicate to master node.
Master node has all nodes defined but when I try to connect I get error:
proxy02: STATUS_ERROR_CONNECT=co_distribute_status_request: ssl failure on message socket 14 while sending request - last action: certificate verification
I guess, node certificate changed during upgrade, but where to find him ? is it possible to import node cert ? I have backup before upgrade.
BIG thanks for help.
Finally I foud it.
After upgrade, Cluster CA has changed into default McAfee CA ...
So I exported Cluster CA + private key on master node, then logoff and login to management on slave node and imported Cluster CA.
The configuration is now synchronized.
