SSIS 08 job runs a SSRS 08 report but fails when ran in SQL Server

I have created an SSIS package (08) that has a script task which runs an SSRS report (08) with given parameters. The report creates a pdf version of the file on a file share drive of my choosing.

When I run the SSIS manually it works perfectly, however, when I upload SSIS into SQL and then run it from the job agent it fails. It gives a long error message but the basic piece is;

(0xC0016016 Source: Description: Failed to decrypt protected XML node "DTS:Property" with error 0x8009000B "Key not valid for use in specified state.". You may not be authorized to access this information. This error occurs when there is a cryptographic error. Verify that the correct key is available. End Error

Error: 2018-01-15 16:09:58.28 Code: 0xC001600C
Source: PackageSchedule Connection manager "ReportServer08"
Description: Server authentication failed. This error occurs when login credentials are not provided, or the credentials are incorrect. )

I have tried to change the "ProtectionLevel" to "EncryptSensitiveWithPassword" and also "Donset upSensitive".

I setup a subscription to the report just to make sure it wasn't a read/write error to the specific folder and the subscription ran without error as well.

Any help on this would be greatly appreciated.
