The issue seems to be caused by a corrupted secure storage file.
As a workaround, please follow the following steps:
1. Delete your HANA connection on the Navigator tab in HANA Studio, and then close the HANA Studio.
2. Open windows explorer, and navigate to C:\Users\Administrator folder on your Cloudshare desktop.
3. Find the folder ".eclipse" and rename it to "OLD.eclipse":
4. Open your HANA Studio and set your HANA DB Connection again. You will be prompted to set the password reminder for secure storage file. You can choose "No".
5. After that, the new ".eclipse" folder and the new secure storage file will be recreated.
6. Close and re-open your HANA Studio, to verify that the workaround fixed the connection issue.
