If you are unable to add a new Instance via Filter Navigator - Clone - Clone Targets (table: "instance"),

Are you are getting the following error messages:

"Invalid username or password" "Invalid Insert"

"To clone to an instance, you must have admin privileges on the target instance."

Try the following. On the target instance, temporarily disable Multi-factor authentication via Filter Navigator - Multi-Factor Authentication - Properties (table "sys_properties", record "glide.authenticate.multifactor"). Then try adding the Clone Target again. Then re-enable MFA on the target instance.
