HCP Productive instance locked during upgrade

Hi experts,

I have a productive instance in the Hana Cloud Platform. Today I triggered the update process from the HCP Cockpit and an error occurred in step "Updating System". The error details are given below:

Process ID: 56654

Error message: Error occurred during update

Troubleshooting: Contact SAP support and provide the process ID.

After this error my system got locked and I'm not able to perform work on my Hana artifacts (Calculation views, roles, etc.).

My account ID is b4b86a385. Could you please help me solving this issue?

Regards,

Gustavo
