Unable to find the common symmetric key

[Daljith]

Hi Cognoisers,

This morning few reports failed suddenly and when I checked the log, I found below message.  I am surprised because no one have access to configuration folder except me. Anyone aware of any specific reason, why suddenly without any manual interference, the symmetric key can have issue.

found the issue. Keys has expired. I regenerated the keys.

was just checking below article on setting the keys value to more than 365. I am planning to change it to 5 years (1825).

Though the article says the value can be set to any number.
If anyone can suggest if it can create any problem or what maximum value can be set for this.
