[Landlord - US - FL] rent late due to marines not paid?

What would you do about a tenant not paying rent? It is now seven days late, no advance notice and no communication. I have to message her multiple times with no response. She finally responded with the fact that her ex is in the marines and they are not getting paid for the government shut down. So she doesn’t have the child support money she would normally get to pay rent. This is not the first time Rent it’s been late. She moved in in August and is only paid rent on time in October. I do have late fees, but really just curious what to do in this situation? Is there something I need to excuse or should she be paying rent even without child support money?
