Receiving 403 Forbidden message when trying to pilot experiment on Pavlovia

Hello! I’m very new to Psychopy and Pavlovia and am trying to setup up my experiment. I was able to sync it from Psychopy to Pavlovia. However, when I try to pilot the experiment, I receive a 403 Forbidden message. Is this because I don’t have any credits? Here is my experiment if anyone is willing to give me any suggestions for how to fix this issue: https://run.pavlovia.org/jt2019/experimenttest1. Thank you so much!

OS (e.g. Win10): Tahoe 26.4.1
PsychoPy version (e.g. 2024.2.4 Py 3.8): 2025.1.1
Standard Standalone Installation? (y/n) If not then what?: yes
URL of experiment: https://run.pavlovia.org/jt2019/experimenttest1
Do you want it to also run locally? No. I prefer that it is run online, so that others can access the experiment through a link.
What are you trying to achieve?: I am trying to sync my experiments onto Pavlovia and then run it online.
