Problem with Update to 9.5.1

[M.L]

Hello,

i cant update from 9.3 to 9.5.1. I tried to update via console. At least i have to choice to update if i enter yes or no but only no seems to work.

Her the info i get:

Exchanging information with licensing server.
Downloading the file PSA_9.5.1/plesk_getkeyinfo.sh: 48%..100% done.
Warning: your license key for the base component cannot be upgraded.
Response from the licensing server: Automatic upgrade for this license is not possible. Please contact your reseller.

Continuing with the upgrade without having an appropriate product license key
will result in the installation of a default license key with limited
functionality. Administrators are advised to first acquire the appropriate
license key before continuing with the product upgrade.

Do you want to continue?
Type either Yes or No:
[N]:

Could someone help me please. The license is leased from strato.

Thanks

You must type "Yes" all other versions (Y, z, Z, y, YES) aren't working.
