Answer 1

Hi @Santiago S ,

Is this the first time you have encountered this issue? Have you made any changes to the database before?

Encrypt the SSISDB again to see if it is helpful.

open master key decryption by password = 'xxxxx' –‘Password used when creating SSISDB’  
Alter Master Key Add encryption by Service Master Key  

Please also check if you can import the package via SSMS.

Regards，

Zoe

An error occurred during decryption.

Which ProtectionLevel have you selected for the package and if with password, have you provided the right one for decryption during deployment?
