403 error when trying to run online

PsychoPy version: 2025.2.3beta
URL of experiment: https://run.pavlovia.org/HLove/BART_Task_NEW

I’m trying to run a BART task I have created in psychopy builder in a browser so that participants can access it online at home etc. The task runs locally and I have linked to pavlovia/gitlab, but whenever I try to pilot or run it comes up with a 403 error. Can anyone help me fix this please?

UPDATE: I have uploaded more files to gitlab (i.e., html). When I pilot or run now through pavlovia it says ‘[Init] Please wait a moment…’, but doesn’t ever actually load the experiment. Any advice?
