Student loan application denied due to one recent late payment on a credit card

I applied for a student loan with Citizens Bank with a cosigner. We both have good credit scores. However, I recently opened a new credit card and I missed the last payment deadline because I thought that I had set up an autopay (but actually hadn't). My student loan application was denied for “credit history reflects one or more trade lines over 30 days late".

I have just paid off the credit card. It was totally my mistake.

What actions can I take to get the student loan application approved? When is the earliest I can try again? Thank you!
