May be I found the problem but I don't know what should I do? Time ago I deleted the Default Cluster from the WebAdmin but it still be in the database. Do you know if I can delete from the database without have any problem? engine=# select vds_group_id, name, description, compatibility_version from vds_groups; vds_group_id | name | description | compatibility_version --------------------------------------+---------+----------------------------+----------------------- 00000001-0001-0001-0001-00000000002b | Default | The default server cluster | 3.5 b90fb2b7-e6ae-4f50-a41e-4cc4044d769d | Mendoza | | 3.6 0ccf2c40-7feb-40f7-826e-b225f3a58b71 | Prueba | | 3.6

Check in the UI if you can increase the cluster level to 3.6 (if it's still not set).

Do you have any idea about how to solve that?
