Possible causes of "not a valid verified trial request file"

Hi Wyatt,

We have a customer who is in a restricted internet environment and we have to do offline trial activation for him.When I try to activate the trial on wyDay website with the trial request file that he sent me, I got the following error message, "This is not a valid verified trial request file trial activation block failed to decode."It might be worth mentioning that the offline trial activation flow used to work with this customer on a different machine just a few days ago. The trial request file is pasted below.

Could you please tell us what are the possible causes of this error to help us troubleshoot the issue? Thank you!
