Pre-seed investors fell through. Is it ok/a red flag to reach out to others who investors I previously rejected? (I will not promote)

I previously thought I was going to successfully close out my pre-seed round so I told some interested investors that I wasn’t accepting any more investments. Unfortunately, some investors pulled out at the last second and I find myself in a situation where I need to raise additional funds to replace the flaky investors’. Is it a red flag to investors if I reach back out to them saying I need to raise more after all?
