SYSTEMDB - HANA STUDIO - Unable to connect

Hello,

My SAP HANA DB was upgraded from 2.0 SPS 0 to 2.00.037

I'm trying now to connect to SYSTEMDB from HANA Studio but this is not possbile. SYSTEM password was reset but still the connection doesnt work. The only way I can access it is from OS level with hdbsql. Any suggestions please? I can connect only over the tenant with SYSTEM and any other users.

Regards,

Florin
