Renter’s insurance mess up

I messed up big time. We moved onto a military base for the first time in 2 years. We signed our lease but I didn’t get renter insurance set up until 3 days after our move in date. When we were originally sent the lease it was only to my husband, while in previous years it was to me as well. Yes they had my information but he was the only one on the lease. This is causing issues with housing, while they haven’t told us what yet I’m worried about a lease violation and eviction. our insurance company was not able to backdate it for obvious reasons and this was 100% on me for getting it done late. I just need to know all possibilities and how i could possibly remedy the situation. I’m freaking out as we just did a cross country move with a newborn and living off base is too expensive for our family of 4.
