HANA 2.0 SPS1 upgrade error: Execute failed (-10821): Session not connected

Dear all,

I need to upgrade ours HANA 1 SPS12 to HANA 2 SPS1. Ours HANA system is installed as single container and one of the steps during system upgrade is convert single container system to multi container system.

Unfortunately I am getting some error during this upgrade:

What could cause this error messages?

I tried to deactivate local firewall on the server and start update process again, but after firewall deactivation I am getting the same error message.

Thank you so much,
