Useful label for message box cancel/close button

i'm reworking a message box that pops up when there was a specific error.

In the title and description it tells the user what went wrong. In the improved version i will include 2 buttons (in the current version there's only a close button captioned 'ok')

1 button which is the primary button links them to a contact form where they can get help from customer service. it is labeled 'contact. the 2nd button will close the box, and its labeled 'try later'.

My question is, does the 2nd button label make sense, giving it will close the box. would there be a better caption to this?
