Hi
I did the update to 10.4 and had again some troubles with Cert and Passwords on Windows / Hpyer-V Hosts.
After some tests I found the following way to get it running.
Bevor you start the Update:
Create a copy of your current Nakivo Directory on C:\Program Files\NAKIVO Backup & Replication
Do the update, if it's working - be happy
If not:
stop the nakvio service
copy certificate.pem and bhsvc.id from the backup directory to your current directory.
start the service
Refresh the transporter, now it should work
Greetings
Mario
