Is dates in Nov for H1B stamping opened in Chennai?

Hi All, I’m trying to schedule appointment for OFC and H1B stamping interview in Chennai for Nov. When I try to schedule the appointment, I see that only dates till Oct is available and even if I select Oct 30th and go to the next page, I get an error saying “No appointments available at this centre”. Did anyone was able to book the appointment in Nov? The unavailability of dates is freaking me out. I checked with the support team and received a template response. Please respond.
