Payment Plan Not Eligible

Hi! We applied for a payment plant last year and paid it off without any issues. We have been attempting to set up a payment plan again this year but we kept getting a "check again later". Today I attempted again and got a message that we are not eligible for a pre-assessed payment plan. We owe approx $5,000 and already made a $500 payment to the IRS. Is there is a generic reason why someone would get this alert? It was my understanding that one can apply for a payment plan 2 years in a row. We both worked in the same industry and I won my own business as a sole proprietor which I have had for a few years. It is 5/13/2025 today and we filed on time. TIA
